整数型帧间差分JPEG算法及实现

Integer Interframe Differential JPEG Algorithm and It's Realization

本文对静态图象压缩标准JPEG进行了两方面改进，使之适用于运动序列的压缩，并易于在多媒体PC环境下实现．这两方面的改进是：帧间差分消除背景冗余；用CMT变换对DCT变换进行整数运算的逼近．最后给出了一些实验结果．

In the paper, we propose a sequence image compression coding scheme - Integer interframe differential JPEG. Comparing to JPEG , we make use of interframe difference to remove temporary redundancy partially, and C-matrix transform (CMT) to replace DCT. CMT is computationally simpler as it involves only integer arithmetic.
