Özet:

Demand of obtaining better quality image is becoming very important topic in television market. Since many content providers still broadcast videos in SD or HD resolution, upscaling input video to display it on FHD or UHD television with better quality is the key point of image quality. Because basic interpolation algorithms do not satisfy this demand, super resolution algorithms are needed to obtain better quality output video. Therefore, many chip providers claim that their chip supports super resolution algorithms. Throughout this thesis, single-frame and multi-frame super resolution algorithms’ performance and complexity will be investigated to find an optimal algorithm which is able to run on Linux televisions in real-time. Moreover, effect of the motion estimation on multi-frame super resolution algorithms will be investigated. As a second contribution of this thesis, mmrgLibrary will be presented. This image processing library is developed in order to unify all the third party libraries into one library and in order to implement customize algorithms. This library is cross-platform API which can be executed on ARM platforms, X86 platforms or any platforms if the toolchain of this platform is provided.
