摘要

提出了一种新的基于dct的帧内编码算法。该算法通过将图像中相似的块分组到一个类别中来利用块间的相关性。然后用JPEG算法对类别的中心进行编码。仿真结果表明，与JPEG相比，该算法在低比特率下显著提高了压缩效率。

DCT-based intraframe coding using block grouping algorithm

This paper presents a new DCT-based intraframe coding algorithm. The algorithm exploits the interblock correlation by grouping the similar blocks in an image into a category. The center of a category is then encoded with the JPEG algorithm. Simulation results indicate that the proposed algorithm improves the compression efficiency significantly at low bit rate, as compared to JPEG.
