| Abstract: | The article analyzed the problems faced in cross-media color image transmission,and then introduced the key techniques of color image transmission,gamut conversion and gamut mapping.On the basis of analysis on the executive mechanism of gamut conversion and gamut mapping,the determination of gamut boundary was discussed,and then the concept and application of gamut compression and gamut clipping were introduced.Finally,the most popular algorithms in the field such as SLIN and CUSP were narrated in detail and then evaluation was given on them. |
