This paper deals with a novel method of image compression. The proposed algorithm targets the psychovisual redundancy in the given image to improve compression. The properties or features of the image are initially modified (while ensuring that the image quality is not deteriorated) by down sampling along the horizontal and vertical dimensions. The transform is then applied on this modified image obtaining a better PSNR after compression than on the original image. The results obtained are
