The Optimization Selection Algorithm of Coding Model Based on Object
|
Abstract:
Various video compressed coding standards are established in the sphere of difference according to people for the requirement of the data of voice and image,and developed continuously along with the demand of people. Now, video compressed coding research divides into two directions mainly:One is that DCT hybrid encoding scheme based on tradition;another is the coding scheme based on object of putting forward based on 2 generation image coding tech- nology. The coding method based on object,can not only satisfy the function that gets the requirement of larger image data compression ratio further and can realize man-machine interaction,so we think it will be future video compressed coding develop direction. In this paper,we study selection algorithm of the coding model based on object,and give the method of video cuts apart using the concept of video object in MPEG-4.
