In this paper, a new color transform for image compression is introduced. Weights of the color transform are determined using the histogram of an image, making it image-specific. The compression efficiency of the transform is demonstrated using the JPEG image coding scheme. The suggested transformation results in better PSNR values than original JPEG for a given compression level when tested on 15 commonly used test images.
