Abstract: Today is the world of digital processing and here everyone wants the image with better quality with high resolution. In the image processing lots of functions are used to increase the quality of color image. Previously CID (Color Image Difference) metric is used to remove the artifact and increase the color quality of image but still some artifact remains present in image. For removing visual artifact there is needed to do the modification in the objective function. After doing the modification in the CID metric new objective function is found named as ICID (Improved Color Image Difference). CID based enhancement is free from visual artifact and retain the contrast, structure and exceed the color quality of image to the great extent. The CID function is also used for different file format and different size of image. In this paper we compare the gamut mapping and the emboss filter by calculating the iCID metric. Emboss filter do the better work on edges and the lightness inversion of the visual data.
