Varible blocksize motion estimation for H.264

Abstract

Digital video coding plays a vital role in Transmission of videos. A still image will not contain any temporal content but possesses only spatial information but video does. Main key point for video compression is Motion Estimation. The clarity of the reconstructed video depends on how best we estimated the motion between two successive frames. Motion Estimation is done by Block matching algorithms. In this paper six algorithms are explained & applied on different styles of videos like slow motion, medium motion, fast motion. The comparison results will give the summary and the best algorithm suitable for different category of input videos.
