A dynamic rate allocation method is presented which is based on the compression rate of image source coder, channel rate, channel characters and their influence on the distortion of progressive image.
The image data of the photo set was compressed with IBR compression algorithms such as the block coder, the reference coder and multidimensional wavelet transform.
再用块编码、参考编码和高维变换(小波)编码等三类I BR压缩系统对照片集图像数据进行压缩。

First, the theoretical foundations of wavelet based video coder as well as a new video coder for low bit rate video compression used in this research are presented.
