基于优化后的量化表、哈夫曼表编码的JPEG文件格式的码流进行快速解析研究,提出了MCU块快速定位算法,该算法通过输入MCU块号来对每个MCU块进行快速定位以及显示当前MCU块的系数情况及具体详细解码过程。

In this paper, the code flow of JPEG file format has been rapidly analysized and studied based on optimized quan- titative table and huffman table. This paper has put forward the MCU block fast positioning algorithm. Through the input MCU block number, it can get each MCU block of rapid positioning and display the current coefficient,...
