Image segmentation is an important research area in digital image processing with several applications in vision-guided autonomous robotics, product quality inspection, medical diagnosis, the analysis of remotely sensed images, etc. The aim of image segmentation can be defined as partitioning an image into homogeneous regions in terms of the features of pixels extracted from the image. Image segmentation methods can be classified into four main categories: 1) clustering methods, 2) region-based methods, 3) hybrid methods, and 4) bayesian methods. In this thesis, major image segmentation methods belonging to first three categories are examined and tested on typical images. Moreover, improvements are also proposed to well-known Recursive Shortest-Spanning Tree (RSST) algorithm. The improvements aim to better model each region during merging stage. Namely, grayscale histogram, joint histogram and homogeneous texture are used for better region modeling.

Autofluorescence retinal images are obtained with a confocal laser scanning ophthalmoscope, and used for the diagnostic of glaucoma. Glaucoma causes a gradual death of nerve cells and can cause blindness. Retina autofluorescence is caused by pigment lipofuscin, which causes cell damage. The aim of this work was to study methods suitable for segmentation of autofluorescence zones and method for tracking objects in an image. In this project was implemented algorithm of autofluorescence zone detection using method of region growing, designed and realized method for tracking autofluorescence regions.

Магистерская диссертация посвящена поиску эффективных методов коммуникации между общественными и культурными организациями, с одной стороны, и властью, с другой, при работе над формированием имиджа региона. Как показало проведенное исследование в Свердловской области, несмотря на богатство ее культурных ресурсов, доминантным является физико-географический имидж. Причина этот на наш взгляд лежит как в отсутствии у властей представления о том, каким должен быть имидж региона а так же в непоследовательности и стихийности культурной политики. В этих условиях основной используемой общественными организациями GR технологией остается выстраивание личной коммуникации с лицом, принимающим решение. Для улучшения коммуникативной стратегии общественных организаций по взаимодействию с органами власти нами были разработаны предложения, в основе которых лежит расширение своего влияния на власть посредством СМИ, союза с другими общественными структурами и активного участия в политической жизни. / The master thesis is devoted to search of effective methods of communication between the public and cultural organizations, on the one hand, and the power, with another, during the work on formation of image of the region. As showed the conducted research in Sverdlovsk region, despite richness of its cultural resources, physiographic image is prepotent. The reason this in our opinion lies as in absence at the authorities of idea of what has to be image of the region and also in inconsistency and spontaneity of cultural policy. In these conditions the main technology used by public organizations GR there is a forming of personal communication with the person making the decision. For improvement of communicative strategy of public organizations for interaction with authorities we developed offers which cornerstone expansion of the influence on the power by means of mass media, the union with other public structures and active participation in political life is.
