The main intention of this work is to find out, what is image of organization and what are the main elements having influence to image formation. On the first part of this work there are defined image of organization on the ground of many authors books about marketing and public relations. On the contents of this theory there are made a researching about image of Vilnius Pedagogical University. There are used VPU student’s opinions about image of VPU. Questioning inquiry was made between students of all faculties of this university from day and evening sections. Totally 470 students participate in this researching. There are three propositions for this analysis: 1) To definite the image of organization; 2) To display VPU image from students sight; 3) To display elements, which makes influence to image of VPU. The object of research is image of VPU, and elements, which makes influence to image of VPU. The subject of research is VPU student’s opinions. There are five hypotheses. 1) Student’s opinions about VPU image are rotating to good direction. 2) The mission of VPU - to qualify pedagogues, is not the mine reason for students of option to study in VPU. 3) Pedagogue’s competency and profession skills, behavior and ethic – elements determinate not very high culture of VPU organization. 4) There is deficiency of interest to study in VPU. 5) The study environment students value good enough. Almost all hypotheses were proved, except the last one about study environment... [to full text]

Postgraduate studies final work of university consists of 60 pages, 27 figures, 3 tables, 68 references, 25 appendixs. It is written in Lithuanian language. The research object of this work is the image formation of the three branded meat shops in the Mažeikiai. The research aim- to create work of specialized meat shops reputation. Objectives analysis the sense of organization reputation and create run; to explain the ways of organization image; to examine the most important models of image making and to evaluate their advantages and disadvantages; to investigate the factors, that have influence in image formation; to present general theoretical model of mini shops image formation. In the process of research were used different methods. In the theoretical part of the thesis was used a comparative analysis and discussion on the concept of image. A questionnaire was used as a quantitative research method with meat product consumers in Mazeikiai. Receive results was generalized with statistical methods and graphs. Besides in the process of research was used the verbal documents analysis and a personal observation. The first chapter “Image essence of the organizations and peculiarity of it formation” is intended to review what is the reputation of organization and what are the principles of image found. The special attention was focused on the research models and methods of organization image. Up to now boffin of management found 7 models of organization reputation and... [to full text]

Το ερευνητικό αντικείμενο της συγκεκριμένης διατριβής αναφέρεται στην επεξεργασία έγχρωμης εικόνας με χρήση της θεωρίας γράφων, την ανάκτηση εικόνας καθώς και την οργάνωση / διαχείριση βάσεων δεδομένων με μεθόδους γραφημάτων και αναγνώρισης προτύπων, με εφαρμογή σε πολυμέσα. Τα συγκεκριμένα προβλήματα προσεγγίστηκαν διατηρώντας τη γενικότητά τους και επιλύθηκαν με βάση τα ακόλουθα σημεία: 1. Ανάπτυξη τεχνικών για την επιλογή χαρακτηριστικών από τις εικόνες βάσει χαρακτηριστικών χαμηλού επιπέδου (χρώματος και υφής), για χρήση τους σε εφαρμογές ομοιότητας και ανάκτησης εικόνας. 2. Υπολογισμός μετρικών και αποστάσεων στο χώρο των χαρακτηριστικών. 3. Μελέτη της πολυσχιδούς δομής των εικόνων μιας βάσης στο χώρο των χαρακτηριστικών. 4. Ελάττωση της διάστασης του χώρου και παραγωγή αναπαραστάσεων δύο διαστάσεων. 5. Εφαρμογή των μεθόδων αυτών σε υποκειμενικές αποστάσεις εικόνων. Η θεωρία γράφων και οι μέθοδοι αναγνώρισης προτύπων χρησιμοποιήθηκαν προκειμένου να παρουσιαστούν βέλτιστες λύσεις αφενός στο πρόβλημα της ανάκτησης εικόνων από βάσεις δεδομένων και αφετέρου στην οργάνωση και διαχείριση τέτοιων βάσεων εικόνων. Η διατριβή φέρνει πιο κοντά την επεξεργασία εικόνας με μεθόδους προερχόμενες από τη θεωρία γραφημάτων, τη στατιστική και την αναγνώριση προτύπων. Σε όλη τη διάρκεια της διατριβής, ιδιαίτερη έμφαση δόθηκε στο ζήτημα της εύρεσης του κατάλληλου συνδυασμού μεταξύ της αποτελεσματικότητας των συστημάτων και της αποδοτικότητας στα πλαίσια της εφαρμογής των προτεινόμενων αλγοριθμικών διαδικασιών. Τα αναλυτικά πειραματικά αποτελέσματα που πραγματοποιήθηκαν, αποδεικνύουν την βελτιωμένη απόδοση των προτεινόμενων μεθοδολογιών. / The subject of this doctoral thesis is related to color image processing using graph theoretic methods, image retrieval and image database management and organization in the reduced feature space, using pattern recognition analysis, with multimedia applications. The author attempted to approach the thesis subject by retaining its genericness and addressing the following points: 1. Development of techniques for extraction of image visual attributes based on low level features (color and texture information), to be used for image similarity and retrieval practices. 2. Calculation of metrics and distances in the feature space. 3. Study of the image manifolds created in the selected feature space. 4. Application of dimensionality reduction techniques and production of biplots. 5. Application of the proposed methodologies using perceptual image distances. Graph theory and pattern recognition methodologies were incorporated in order to provide novel solution to color image retrieval of image databases, as well as to image database management and organization. The current thesis brings closer image processing with graph theoretic methodologies, statistical analysis and pattern recognition. Throughout the thesis, consideration has been taken for finding the best trade off between effectiveness and efficiency when applying the proposed algorithmic procedures. The extended experimental results carried out in all stages of the projected studies reveal the enhanced performance of the proposed methodologies.
