Firstly, chromatism analysis and wavelet transform are used for color image compression coding. in this method, one of the three color components of a color image ( for example the g component of a rgb color image ) is coded using wavelet transform, and the chromatism between g and other two color components rg = r - g, bg = b - g is coded respectively using chromatism analysis. during decoding, g ~ is first reconstructed using wavelet inverse transform and inverse quantisation, and rg, bg are reconstructed using chromatism analysis inverse transform ; then r, b are calculated by r = g + rg and b = g + bg respectively
其一是應用色差分析和小波變換對彩色圖象進行壓縮編碼，該方法是對彩色圖象的三個色彩分量之一，如rgb圖象的g進行小波變換編碼，而對g與另兩個色彩分量的差值（即rg = r - g和bg = b - g ）進行色差分析編碼，解碼則是通過反量化和小波逆變換得到g ^ ，通過色差分析的逆變換得到兩個重構的色差rg ^和bg ^ ，再算出r ^ = g ^ + rg ^ 、 b ^ = g ^ + bg ^ ，最後由r ^ 、 g ^ 、 b ^重構圖象。 -
