JPEG采用的是YCrCb颜色空间，而BMP采用的是RGB颜色空间，要想对BMP图片进行压缩，首先需要进行颜色空间的转换。YCrCb颜色空间中，Y代表亮度，Cr,Cb则代表色度和饱和度(也有人将Cb,Cr两者统称为色度)，三者通常以Y,U,V来表示-JPEG is used in YCrCb color space, and BMP is used in RGB color space, to compress the BMP image, we need to perform color space conversion. In YCrCb color space, Y represents the brightness, Cr, Cb represents the hue and saturation (there are Cb, Cr both collectively referred to as chroma), three Y as usual, U, V.
