Description: 一个原始图像信息，要对其进行 JPEG 编码，过程分两大步：
i) 去除视觉上的多余信息，即空间冗余度
ii)去除数据本身的多余信息，即结构（静态）冗余度
JPEG 编码中主要涉及到的内容主要包括：
i) Color Model Conversion (色彩模型)
ii) DCT (Discrete Cosine Transform 离散余弦变换)
iii)重排列 DCT 结果
iv) 量化
v) RLE 编码
vi) 范式 Huffman 编码
vii)DC 的编码
这部分代码是在DM6446芯片上实现的JPEG编码算法。-An original image information to be JPEG encoded, the process is two step: i) removing excess visual information, i.e. the degree of spatial redundancy ii) to remove the redundant information of the data itself, i.e. structure (static) redundancy JPEG coding mainly related to the content includes: i) Color Model Conversion (color model) ii) DCT (Discrete Cosine Transform, Discrete Cosine Transform) iii) rearrangement of the DCT results iv) quantization v) RLE encoding vi) Paradigm Huffman coding vii) DC coding part of the code is implemented in the DM6446 chip JPEG encoding algorithm.
