| Abstract: | The objective of the paper is to provide an overview on recent development in image and video coding technology.Here,the paper review the rapid development in the field during the past 40 years and outline current state-of-the art strategies for coding images and videos.These and other coding algorithms are discussed in the context of international JPEG,JPEG 2000,MPEG-1/2/4,and H.261/3/4 standards.At last,Some key aspects which are for robustness to data errors/losses and flexibility for operation over a variety of network environments in H.264 Video Coding Standard are introduced in this paper. |
