In this paper, we present a study of video-quality relevant warping parameters. Motivation of our work is to estimate the influence of warping on the quality of videos. This is required for watermarking embedding and attacking approaches that base on warping of images or videos. Therefore, we propose a universal set of parameters, which can be used to describe any warping field. Aim is to estimate out of these parameters the video quality after warping. To show the correlation between parameters and video quality, we performed a study and present the results in this paper.
