The Software Realization of MPEG-4 based on video surveillance application
Li Qing-ping , Shi Zhong-suo,Chen Ming (University of Science and Technology beijing, Information Engineering Institute, beijing,100083)Abstract Due to the characters of video surveillance, this paper mainly discusses the softwarerealization of MPEG-4 based on video surveillance application. Also the related key techniquesincluding the generation of VOP, shape coding, texture coding, motion coding are presented andthe novel techniques that do not appear in the previous standard are emphasized, for example,Sprite coding and scalable coding.
Key words MPEG-4, VOP generation, Sprite coding, Scalable coding
