MULTIRESOLUTION QUALITY EVALUATION OF GEOMETRICALLY DISTORTED IMAGES

In multimedia applications there has been an increasing in-terest in the use of quality measures based on human percep-tion, however, only few works have dealt with distortions due to geometric transformations. In this paper we describe the solutions proposed so far in the literature for the quality evaluation of geometric distortions in images and we im-prove the performances of two recently described metrics with the introduction of a multiresolution framework and a perceptibility map. The results show the good performances of the proposed techniques compared to the previous ver-sions of the metrics. 1
