SpecialVIJPG
- 自己的开源小项目：JPEG分析器。JPEG全称是 Joint Photographic Experts Group（联合图像专家小组），是当今使用最为广泛的图像编码标准。我这个项目规模不大，主要可以用来学习JPEG编码标准。结合着源代码看的话效果比较好。它支持将JPEG解码为像素数据（YUV或者RGB）。同时支持输出DCT系数等参数。使用VC 2010的MFC开发完成。 详细参考： http://blog.csdn.net/leixiaohua1020/article/details/1
Image-Compression
- DCT变换1、 提取彩色图像，将图像大小限制为512* 3； 2、 提取彩色图像三个颜色分量的矩阵，每个矩阵单独处理； 3、 将矩阵分为8*8的块，做DCT变换； 4、 提取每个块的一部分DCT系数做IDCT变换，显示基本图像； 5、 再提取每个块的一部分DCT系数做DCT反变换，得到增强层1，与前一次得到的数据叠加，得到质量更好的图像。 -DCT transform
