Korekce snímků / Picture correction

Sedlo, Petr January 2016 (has links)
This work is focussed on different unwanted effects that damage a digitally acquired image. An image acquired using a digital camera can suffer from a series of defects. First, the noise is concerned. It occures due to discretisation. Next, there are the defects including vignetting, radial image distortion, chromatic aberration. In my thesis I also worked on backlight image compensation and panorama creation from an image sequence. For backlight images we need to increase the brightness in the dark parts of the image, so that the details became more visible. At panorama creation we are careful about brightness evenness in partial images, which is usually not conserved and consequently we try to find a suitable boundary-line to connect images and smooth it. The fundamental part of my work was writing the algorithms that are able to compensate these defects at least partly. For this aim I took use of the Matlab environment.

Анализ социальных медиа как инструмента корректировки имиджа экологически неблагополучного заполярного города : магистерская диссертация / Analysis of social media as a tool of correcting the image of an environmentally disadvantaged polar city

Карунас, А. А., Karunas, A. A. January 2020 (has links)
В контексте ярко выраженной территориальной конкуренции, возрастающей роли социальных медиа в нашей повседневной жизни, важным аспектом развития территории становится создание и коррекция её имиджа в сети интернет. Норильск не является исключением. Ввиду особого арктического климата, экологических проблем города, а также слабой изученности маркетинговых инструментов продвижения подобных территорий, в нашей работе мы изучили опыт сторонних авторов, провели собственные исследования и разработали программу корректировки имиджа города, применимую к территориям с подобными характеристиками и проблемами. Для этого мы изучили сущность понятия «имидж города» и инструментов его корректировки, специфику социальных медиа, а также российский и зарубежный опыт корректировки имиджа. Также мы определили основные характеристики города Норильска, изучили мнение его жителей и мнение экспертов относительно имиджа территории, провели контент-анализ социальных медиа и оценили работу властей города по корректировке имиджа в сети интернет. Все это позволило нам разработать программу, рассчитанную на создание положительного имиджа территории инструментами социальных медиа. / In the context of territorial competition and the increasing role of social media in our daily life, the creation and correction of its image on the Internet becomes an important aspect of the development of the territory. Norilsk is no exception. Due to the special Arctic climate, ecological problems of the city, as well as lack of knowledge of marketing tools for promoting such territories, in our work, we studied the experience of other authors, conducted our own research and developed a program for correcting the image of the city, which can be used by other territories with similar characteristics and problems. To do this, we studied what the "image of the city" is and the tools for its correction, the specifics of social media, as well as Russian and foreign experience of image correction. We also identified the main characteristics of the city of Norilsk, studied the opinion of its residents and experts about the image of the territory, conducted a content analysis of social media and assessed the work of the city administration to adjust the image on the Internet. All this allowed us to develop a program designed to create a positive image of the territory using social media tools.
