摘要：

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.
