Various contemporary standards by Joint Picture Expert Group, which is used for compression, exploited the correlation among the color components using a component color space transform before the subband transform stage. The transforms used to de-correlate the colors are primarily the fixed kernel transforms, which are not suitable for large class of images. In this paper an image dependent color space transform (ID-CCT), exploiting the inter-channel redundancy optimally and which is very much suitable for compression has been proposed. Also the comparative performance has been evaluated and a significant improvement has been observed, objectively as well as subjectively over other quantifiable methods.
► This paper presents a novel adaptive color space transformation.
► This transform is applied to image compression.
► The proposed color space transform is based on SVD.
► The objective as well as subjective performance is found quite convincing.
► Also the ID-CCT may be applied for various other image processing applications.
