| 8. | 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
其一是应用色差分析和小波变换对彩色图象进行压缩编码，该方法是对彩色图象的三个色彩分量之一，如rgb图象的g进行小波变换编码，而对g与另两个色彩分量的差值(即rg = r - g和bg = b - g )进行色差分析编码，解码则是通过反量化和小波逆变换得到g ^ ，通过色差分析的逆变换得到两个重构的色差rg ^和bg ^ ，再算出r ^ = g ^ + rg ^ 、 b ^ = g ^ + bg ^ ，最后由r ^ 、 g ^ 、 b ^重构图象。 |
