....image features will fare poorly in PSNR, but not necessarily for an observer. The problem of improved distortion measurements is quite difficult. For that reason this work uses PSNR exclusively. Discussion of applying information about the human visual system to distortion metrics may be found in [45, 13]. There has been some work done in application of such metrics to image compression, for example [42] To compare performance under these measurements of rate and distortion it is convenient to produce rate distortion curves. For example, Figure 4.3 shows the results of several different coders ....

....z color space. images to match, the data should be processed in the same coordinate system used by the human visual system. Experiments show that spatial frequency response of the visual system is due to the combined e#ects of optical blur and the limited resolving power of the retina brain system[19]. Recent studies have found that the fall o# in contrast sensitivity at high spatial frequencies is mainly due to optical properties of the eye[20] Since optical blurring e#ects are due to incoherent averaging of energy, these e#ects are properly modeled by filtering in a color coordinate system ....
