| 摘 要： | 分形视频压缩建立在静止图像分形压缩的基础上,其压缩思想主要是对Jacquin分块方法的扩充,把二维的值域块和定义域块扩充成三维值域立方体和定义域立方体,或者采用帧间的分形压缩和帧内运动补偿相结合的办法。这两种方法所具有的大计算量限制了分形视频压缩的研究和应用。该文沿这两个思路引入了分布并行计算机制,从而缩短了压缩时间。

| Abstract: | Fractal compression of video sequences is based on fractal still image compre ssion.The main methods are the extension of Jacquin partition method,that is, extending two -dimensional range blocks and domain blocks to three -dimensiona l range cubes and domain cubes,or combining intra -frame fractal compression with inter -frame motion compensation.The huge computing complex of all these methods restricts the studies and applies of fractal video compression.This pa per studies the distributed parallel method of the fractal video compression whi ch can shorten the run time of fractal video compression. |
