Abstract

We present in this paper the results of our study on the human perception of geometric distortions in images. The ultimate goal of this study is to devise an objective measurement scheme for geometric distortions in images, which should have a good correspondence to human perception of the distortions. The study is divided into two parts. The first part of the study is the design and implementation of a user-test to measure human perception of geometric distortions in images. The result of this test is then used as a basis to evaluate the performance of the second part of the study, namely the objective quality measurement scheme. Our experiment shows that our objective quality measurement has good correspondence to the result of the user test and performs much better than a PSNR measurement.
