An important technique in image and video processing is global motion estimation (GME). The common GME methods can be classified in direct and indirect categories. Whereas the direct global motion estimation techniques boast reasonable precision they tend to suffer from high complexity. As with indirect methods, though presenting lower complexity they mostly exhibit lower accuracy […]
Progress of technology in recent decades causes that video transmission via communication channels has met high demands. Therefore, many methods have been proposed to improve the quality of video under channel errors. The aim of this paper is to increase PSNR for video reconstructed by the receiver; this is achieved by increasing channel encoder rate […]
