- This a JPEG codec with AC/DC Huffman entropy coding, 4:2:0 Sampling, RGB/YCbCr converter. 2D-DCT and Quantization is included in the JPEG_Main. There also a Huffman table list in .txt, two sample testing picture and the bitrate-PSNR , Compressi
rgb2ycbcr
- rgb轉YCbCr，4:2:0。分割成yCbCr有三個圖，就是YCbCr(4:4:4)，CbCr再去降取樣成1/4，就變成4:2:0。 最後再轉回rgb。 -rgb to ycbcr。 rgb change to ycbcr 4:4:4 4:4:4 change to 4:2:0，four value divide by 4 equal to a value. Ycbcr(4:2:0) to rgb.

double-ellipses-skin-color-model
- 在复杂背景下双椭圆模型结合在CbCr和CgCr平面内体现的肤色聚集性和集中性的检测效果要比单高斯模型的效果好。在YCbCr和YCgCr颜色空间中，虽然Y分量和Cb、Cr、Cg分量表示的性质看似是相互独立的，但它们都是建立在红、绿、蓝三个基本颜色分量值的基础上算出来，因此它们之间仍然存在着千丝万缕的关系。根据肤色在两种色彩空间中体现出的聚集性提出CbCr-CgCr双椭圆肤色模型-Good background in complex dual oval model incorporated with
