- 提示: JPEG压缩分为三个部分: 1.JPEG压缩原理及算法(RGB/YCbCr,DCT/IDCT,量化,Z字型编码,用DPCM对DC/用RLE对AC编码/Huffman编码) 2.JPEG标记格式 3.JPEG图片文件的组织形式(位于SOS后的图像压缩数据是由MCU块怎样排列的,特别是使用了DRI之后) 还有许多细节问题: 1.解码过程中遇到“FF 00”当“FF”处理,否则忽略“FF” 2.进行DCT前YCbCr要减128,进行IDCT前要加128(相当于Y减128,YCbCr不需要加12
Huffman
- 使用huffman进行图像的编解码, 使用简单易懂-encoding/decoding the image using huffman
Player+Demo+Source
- 本解码器类支持普通jpeg文件格式,这也是目前大多数jpeg文件所采用的格式,此格式主要特点是数据精度为8位,采用Huffman编码的普通DCT帧(不支持扩展串行和递进模式及数学编码)。本解码器类的IDCT算法采用三种模式,分别是浮点解码、定点整数解码和定点整数MMX优化解码,您可根据具体情况选择。-The decoder supports the general category jpeg file format, which is most used in jpeg file format
