Opis:: The study focuses on the three main types of the image of PR manager - self-image, perceived image and professional image. Its purpose is to identify all the image attributes needed for a position of PR manager. In the theoretical part, image is defined as the combination of both external and internal reflections of an individual, object or company creating values and awareness. The research part is the application of theoretical principles in the practical operations of three PR managers from the insurance sector and four PR managers from the bank sector. Research is in the form of an 8-question structured interview and qualitative response analyses. The result of the issue is an empirical assessment of the gathered information, studied literature and research. In self-image description the managers describe themselves as creative, systematic, reliable, extrovert, social with excellent communication skills. The perceived image of PR managers requires responsibility, friendliness, helpfulness, politeness and empathy. The professional image of PR managers requires a professional dress code, responsibility, creativity, excellent communication skills, openness to new ideas and experiences. Primary analytical and organizational attributes are considered as an advantage in the profession of PR manager as well.

Opis:: We propose a high-quality infrared and visible image fusion method based on a deep wavelet-dense network (WT-DenseNet). The WT-DenseNet includes three network layers, the hybrid feature extraction layer, fusion layer, and image reconstruction layer. The hybrid feature extraction layer is composed of a wavelet and dense network. The wavelet network decomposes the feature map of the visible and infrared images into low-frequency and high-frequency components, respectively. The dense network extracts the salient features. A fusion layer is designed to integrate low-frequency and salient features. Finally, the fusion images are outputted by an image reconstruction layer. The experimental results demonstrate that the proposed method can realize high-quality infrared and visible image fusions, and the performance of the proposed method is better than that of the six recently published fusion methods in terms of contrast and detail performance.

Opis:: Large-scale image repositories are challenging to perform queries based on the content of the images. The paper proposes a novel, nested-dictionary data structure for indexing image local features. The method transforms image local feature vectors into two-level hashes and builds an index of the content of the images in the database. The algorithm can be used in database management systems. We implemented it with an example image descriptor and deployed in a relational database. We performed the experiments on two image large benchmark datasets.

Opis:: The aim of this paper is to verify the capacities and limitations of the newspaper column (understood as a genre) as a tool for creating the image of its author. In the paper, the distinguishing features of a column are first presented, and then a hypothesis is proposed for predicting which attributes of its author may be generated by the column’s features. This hypothesis is juxtaposed with the results of empirical research. The main task of this research was to read the texts of one of two Polish columnists – Krzysztof Varga and Szymon Hołownia – and subsequently answer questions indicating the authors’ attributes. This procedure made it possible to recreate the image of the text’s author. The results demonstrated the influence of the column’s distinguishing features on the image of its author inferred by readers.

Opis:: Super-resolution image reconstruction utilizes two algorithms, where one is for single-frame image reconstruction, and the other is for multi-frame image reconstruction. Singleframe image reconstruction generally takes the first degradation and is followed by reconstruction, which essentially creates a problem of insufficient characterization. Multi-frame images provide additional information for image reconstruction relative to single frame images due to the slight differences between sequential frames. However, the existing super-resolution algorithm for multi-frame images do not take advantage of this key factor, either because of loose structure and complexity, or because the individual frames are restored poorly. This paper proposes a new SR reconstruction algorithm for images using Multi-grained Cascade Forest. Multi-frame image reconstruction is processed sequentially. Firstly, the image registration algorithm uses a convolutional neural network to register low-resolution image sequences, and then the images are reconstructed after registration by the Multi-grained Cascade Forest reconstruction algorithm. Finally, the reconstructed images are fused. The optimal algorithm is selected for each step to get the most out of the details and tightly connect the internal logic of each sequential step. This novel approach proposed in this paper, in which the depth of the cascade forest is procedurally generated for recovered images, rather than being a constant. After training each layer, the recovered image is automatically evaluated, and new layers are constructed for training until an optimal restored image is obtained. Experiments show that this method improves the quality of image reconstruction while preserving the details of the image.

Opis:: The aim of the paper is to present the issue of brand image transfer in relation to franchising system. In the paper, the meaning of brand knowledge and awareness by customers are described. These two factors are presented as significant tools which companies use to compete effectively in turbulent market. There is presented also a definition of brand and company image transfer as an introduction to the issue of franchising and its role in brand image transfer. The reason of conducting the study is a desire of verification of the mechanism of brand image transfer in franchising. In order to achieve the aim of the paper, the following objectives have been set: (1) to discuss the issue of brand image and customers’ brand awareness and knowledge; (2) to describe the role of franchising in effective brand image transfer; (3) to show the possibilities of influence on brand image in franchising; (4) to point out the consequences (advantages and disadvantages) for both franchisor and franchisee, who decide to be a part of franchising agreement. The literature review and its analysis presented in the paper shows that the image of franchisor’s brand can be transferred to a franchisee’s brands and franchisee’s brand image can be easily transferred to the franchisors’ brand by the customers. These phenomena can be created in the awareness of customers intentionally and unintentionally. That is why the companies have to manage theirs brand image and cooperate if they decide to sign the franchising agreement.
Celem artykułu jest przedstawienie zagadnienia transferu wizerunku marki w odniesieniu do systemu franchisingu. W artykule opisano znaczenie wiedzy i świadomości marki wśród klientów. Te dwa czynniki są przedstawiane jako istotne narzędzia, które firmy wykorzystują, aby skutecznie konkurować na turbulentnym rynku. Przedstawiono także definicję transferu marki i wizerunku firmy jako wstęp do zagadnienia franchisingu i jego roli w procesie transferu wizerunku marki. Główną motywacją do przeprowadzenia badania była chęć zweryfikowania istoty mechanizmu transferu wizerunku marki w procesie franchisingu. Aby osiągnąć cel główny, sprecyzowano następujące cele poboczne: (1) omówienie kwestii wizerunku i świadomości marki, a także wiedzy o niej wśród konsumentów; (2) zaprezentowanie roli franchisingu w skutecznym transferze wizerunku marki; (3) pokazanie możliwości wpływu na wizerunek marki poprzez franchising; (4) wskazanie konsekwencji (zalet i wad) zarówno dla franchisodawcy, jak i franchisobiorcy, którzy decydują się na współpracę w oparciu o umowę franchisingu. Przegląd literatury i jej analiza zaprezentowane w artykule pokazują, że wizerunek marki franchisodawcy może zostać przeniesiony na markę franchisobiorcy, jak i wizerunek marki franchisobiorcy może mieć wpływ na postrzeganie marki franchisodawcy przez klientów. Zjawiska te mogą powstawać w świadomości klientów w sposób świadomy oraz niezamierzony. Dlatego firmy muszą zarządzać wizerunkiem swojej marki i stale ze sobą współpracować, jeśli już zdecydują się kooperować w oparciu o umowę franchisingu.

Opis:: Neutrosophic set (NS) is a powerful tool to deal with indeterminacy. In this paper, the neutrosophic set is applied to the image domain and a novel edge detection technique is proposed. Noise reduction of images is a challenging task in image processing. Salt and pepper noise is one kind of noise that affects a grayscale image significantly. Generally, the median filter is used to reduce salt and pepper noise; it gives optimum results while compared to other image filters. Median filter works only up to a certain level of noise intensity. Here we proposed a neighborhood-based image filter called nbd-filter, it works perfectly for gray image regardless of noise intensity. It reduces salt and pepper noise significantly at any noise level and produces a noise-free image. Further, we proposed an edge detection algorithm based on the neutrosophic set, it detects edges efficiently for images corrupted by noise and noise-free images. Since most of the real-life images consists of indeterminate regions, neutrosophy is a perfect tool for edge detection. The main advantage of the proposed edge detector is, it is a simple and efficient technique and detect edges more efficient than conventional edge detectors.

Opis:: Due to growing demand for ground-truth in deep learning-based remote sensing satellite image fusion, numerous approaches have been presented. Of these approaches, Wald’s protocol is the most commonly used. In this paper, a new workflow is proposed consisting of two main parts. The first part targets obtaining the ground-truth images using the results of a pre-designed and well-tested hybrid traditional fusion method. This method combines the Gram–Schmidt and curvelet transform techniques to generate accurate and reliable fusion results. The second part focuses on the training of a proposed deep learning model using rich and informative data provided by the first stage to improve the fusion performance. The demonstrated deep learning model relies on a series of residual dense blocks to enhance network depth and facilitate the effective feature learning process. These blocks are designed to capture both low-level and high-level information, enabling the model to extract intricate details and meaningful features from the input data. The performance evaluation of the proposed model is carried out using seven metrics such as peak-signal-to-noise-ratio and quality without reference. The experimental results demonstrate that the proposed approach outperforms state-of-the-art methods in terms of image quality. It also exhibits the robustness and powerful nature of the proposed approach which has the potential to be applied to many remote sensing applications in agriculture, environmental monitoring, and change detection.

Autorzy:: Kuca, Magdalena
Opis:: The main goal is to evaluate the image of the Castle Grodziec and to identify directions for it is strengthening. The Grodziec castle image is a mental reflection of the reality perceived by the individual and many factors result in its formation. The representation and opinions about the castle depend on its physical and socio-economic characteristics, its socio-demographic, socio-economic, socio-cultural and psychological features, the activities and opinions of other subjects (eg. the opinion of friends and family, activities of local authorities and other entities associated with the castle), sources from which one derives information about the Grodziec castle. The previous experience of the individual with the place is extremely important in the formation of the castle image.Thesis consists of both theoretical and practical part –for statistical purposes shows the analysis of researches that were carried out using two techniques – poll and interview.
Celem pracy jest ocena wizerunku Zamku Grodziec oraz określenie kierunków jego wzmacniania. Wizerunek Zamku Grodziec jest mentalnym odbiciem rzeczywistości postrzeganej przez turystów, a wpływ na jego powstanie ma bardzo wiele czynników. Wyobrażenia i opinie o Zamku zależą od jego charakterystyki (społeczno-ekonomicznej), jego cech (społeczno-demograficznych, społeczno-ekonomicznych, społeczno-kulturowych, psychologicznych), jak i działań i opinii innych podmiotów (np. opinii znajomych i rodziny, działań władz lokalnych i innych podmiotów związanych z zamkiem), źródeł, z których czerpie się informacje o zamku. Niezwykle duże znaczenie w procesie powstawania obrazu zamku mają także wcześniejsze doświadczenia turystów z tym miejscem. Praca składa się z części teoretycznej oraz z analizy badań przeprowadzonych za pomocą dwóch technik - ankiety oraz wywiadu.

Wydawca:: IET
Opis:: Computer-aided diagnostic is developing rapidly and is being introduced in multiple fields of medicine. One of those fields is dermatology where various types of equipment are used for image acquisition. Those images can be processed in order to assist diagnostic by giving comparative examples, initial image enhancement or automated evaluation. In our research we concentrate on creation of computer-aided methods for skin lesion diagnostics, especially Malignant Melanoma screening based on ABCD evaluation rule [1]. While preparing these methods a number of issues appeared over and over again. The problems are due to the fact that we work with datasets that were obtained from equipment with different characteristics. The methods giving excellent results on one set of images may not perform as well on the others. Solving this problem usually requires manual fine-tuning of a set of parameters. In this paper we introduce a method of automated image adjustment based on color calibration model for calculating the Total Dermoscopy Score (TDS) of the ABCD rule. First we describe the general problem of skin lesion diagnostic and our motivation for the research. Next we will introduce the idea behind the method and its implementation. Finally the practical usage will be shown and discussed.

Opis:: The availability of Sentinel satellites for providing open data with optical and SAR imagery leads to better opportunities related to Earth surface mapping and monitoring. Recently, optical fusion with radar data has shown improvement in classification quality and the accuracy of information acquired. In this setting, the main objective of this research is to monitor the environmental impact of an open-pit mine on water, vegetation, and non-vegetation areas by exploring the single and combined use of Sentinel-1 and Sentinel-2 data. The data utilized in this paper were collected from the European Space Agency Copernicus program. After selecting the Selenica region, we explored the products in the Sentinel Application Platform. According to our data, Sentinel-2 misses the small water ponds but successfully identifies the river and open-pit areas. It mistakenly identifies urban structures and cloud areas as non-vegetated and does not identify non-vegetated areas which correspond to mining operation areas. Sentinel-1 identifies very small water ponds and delivers additional information in the cloudy areas, but misses a part of the river. Alongside the strong contribution in identifying the vegetation, it also roughly identifies the non-vegetation areas of mining operations.

Opis:: Magnetic resonance imaging study is currently the reference method for the detection and diagnosis of the central nervous system tumors. A large number of tumors, especially high-grade, has a higher water content in the cells, which results in prolongation of MRI T1 and T2 what appearance as increased signal intensity in in T2-weighted images and the reduction in T1-weighted images. MRI can be performed with administration of contrast agent, which shortens T1 and increases signal on T1-weighted sequences. This allows to identify areas of increased angiogenesis), which is the exponent of the cancer malignancy degree and its biological activity. Obtained MRI images are analyzed and evaluated by a radiologist and a clinician. Most of the time it is the "by the eye" analysis, which is based on the MRI image evaluation by the generally accepted radiological standards. However, this method is relatively inaccurate. which in turn can bring to the wrong diagnosis of the disease and implementation or even lack of implementation of appropriate treatment. More and more researches are conducted in this area, but developed methods are usually very complicated and difficult to carry out by the "layman" which is the clinician. That is why the attempt is made, to develop a simple and clear algorithm for MRI image analysis in patients with the central nervous system tumors, allowing for quick and objective evaluation of magnetic resonance imaging study.
Badanie metodą rezonansu magnetycznego jest aktualnie metodą referencyjną przy wykrywaniu i diagnozowaniu nowotworów centralnego układu nerwowego. Duża część nowotworów, zwłaszcza o wysokim stopniu złośliwości, charakteryzuje się większą zawartością wody w komórkach, co w badaniu MRI skutkuje wydłużeniem T1 i T2, uwidocznionym jako nasilenie sygnału w obrazach T2-zależnych oraz jego obniżeniem w obrazach T1-zależnych. MRI można przeprowadzić z podaniem środka kontrastowego, co powoduje skrócenie czasu T1 i podniesienie

Opis:: Background: Recent advances in computer technologies have opened new frontiers in medical diagnostics. Interesting possibilities are the use of three-dimensional (3D) imaging and the combination of images from different modalities. Software prepared in our laboratories devoted to 3D image reconstruction and analysis from computed tomography and ultrasonography is presented. In developing our software it was assumed that it should be applicable in standard medical practice, i.e. it should work effectively with a PC. An additional feature is the possibility of combining 3D images from different modalities. Materials/Methods: The program was tested on a PC using DICOM data from computed tomography and TIFF files obtained from a 3D ultrasound system. The results of the anthropomorphic phantom and patient data were taken into consideration. A new approach was used to achieve spatial correlation of two independently obtained 3D images. The method relies on the use of four pairs of markers within the regions under consideration. The user selects the markers manually and the computer calculates the transformations necessary for coupling the images. Results: The main software feature is the possibility of 3D image reconstruction from a series of twodimensional (2D) images. The reconstructed 3D image can be: (1) viewed with the most popular methods of 3D image viewing, (2) filtered and processed to improve image quality, (3) analyzed quantitatively (geometrical measurements), and (4) coupled with another, independently acquired 3D image. The reconstructed and processed 3D image can be stored at every stage of image processing. The overall software performance was good considering the relatively low costs of the hardware used and the huge data sets processed. The program can be freely used and tested (source code and program available at http://www.biofizyka.cm-uj.krakow.pl). Improvements allowing the processing of new data types and new procedures can be implemented for specific demands. Conclusions: The reconstruction and data processing can be conducted using a standard PC, so low investment costs result in the introduction of advanced and useful diagnostic possibilities.

Opis:: Modeling the image of a teacher of higher education is an integral part of the development of modern pedagogical imageology, which is being formed as an interdisciplinary direction. In our study, we analyzed the modern scientific experience devoted to the study of the image of a teacher of higher education. This made it possible to determine the current state of the views of researchers who worked in this direction. The purpose of the article is to highlight the results of research on the content and structure of the image of a teacher of higher education. Summarizing the views of different authors, we formed a general idea of the content of the category of the image of a teacher of higher education, identified the components of the image of a teacher of higher education, identified general characteristics of the image of a teacher of higher education from different positions, components of the image of a teacher of higher education. This allowed us to define the category of the image of a teacher of higher education and to propose an author’s model of systematic description of the image of a teacher of higher education, which is an attempt to find a connection between the components of the image of a teacher of higher education and the environment in which this image is formed. The general components of this model include: determination of the image of a teacher of higher education (sociopsychological aspect, acmeological aspect, activity aspect); bearer of the image of a teacher of higher education; the context of interaction between the bearer of the image and the recipient of the image of a teacher of higher education; symbolic space formed by the bearer of the image of a teacher of higher education; nature of interaction (subject-subject interaction / subject-object interaction); process, forms, types, means of communication; recipient of the image of a teacher of higher education determination of obtaining and accepting the image of a teacher of higher education (activity aspect, acmeological aspect, socio-psychological aspect). Author’s definitions of these categories are given.

Tytuł:: Budowanie wizerunku zewnętrznego na podstawie firm detektywistycznych.
Building an external image on the basis of detective companies.
Autorzy:: Pyryt, Agnieszka
Opis:: Wiek XXI oraz wzrost świadomości społeczeństwa mocno dał się odczuć właścicielom firm, którzy oprócz doskonalenia swoich produktów, umiejętności oraz zdobywania wiedzy musieli skupić się na tym, aby tych klientów zdobyć. Oferowane przez nich usługi nie były wystarczające, gdyż to podaż przewyższa popyt. Z tego względu firmy podjęły się innych rozwiązań, które pozwoliły im na ulokowanie się wysoko na szczeblu rynkowym. Zamierzeniem tych firm jest nakierowanie na tworzenie własnego, oryginalnego wizerunku. Celem niniejszej pracy jest analiza firm detektywistycznych z obszaru Małopolski na podstawie wcześniej wybranych kryteriów, a następnie uzyskanie odpowiedzi na pytanie w jaki sposób firmy detektywistyczny kreują swój wizerunek zewnętrzny. Część teoretyczna jest wprowadzeniem do tematu wizerunku, aby w następstwie tego dokonać analizy.
The 21st century and the rise of public awareness have made a strong impression on the business owners who, in addition to improving their products, skills and gaining knowledge, have had to focus on getting these customers. The services they offered were not sufficient, because supply exceeds demand. For this reason, the companies have taken other solutions that allowed them to position themselves high on the market level. The intention of these companies is to focus on creating their own, original image.The aim of this study is to analyze detective companies from the Małopolska area on the basis of previously selected criteria, and then to obtain an answer to the question of how detective companies create their external image. The theoretical part is an introduction to the subject of image, in order to make an analysis as a result.

Opis:: The great progress in the field of photogrammetry and remote sensing has broken the frontiers of this kind of science. One of the good examples might be Particle Image Velocimetry method. This paper is devoted to the analysis of images recorded by using this particular method. The experiment that we would like to describe took place in the shallow water at the beach near the Gdynia Harbor. We also would like to answer the question, is it possible to trace the trajectories of individual particles?
Postęp jaki nastąpił w zakresie fotogrametrii i teledetekcji spowodował, iż tematyka którą obecnie zajmują się badacze na całym świecie zdecydowanie wykroczyła poza tradycyjne ramy w jakich zwykle postrzega się te dziedziny nauki. Jednym z przykładów jest bez wątpienia anemometria obrazowa. Obrazy generowane przez tą metodę pomiarową są przedmiotem rozważań niniejszego artykułu.
