In this paper we have defined the quantitative measurement for the evaluation of image quality in the discrete cosine transform domain. We have also obtained the algorithm which minimizes the amount of information, making this measurement of quality constant when coding the image. When coding the image the amount of information varies according to the image, but this does not present a problem because we store the images in memory. Furthermore, it is not a problem when we transfer the images if we use only the packet-switched networks. Using computer simulation we found the value of this quantative measurement of the quality of the image to be excellent because the differences between the original and the processed images were negligible.
