In this paper, we propose a blind geometric warping-based watermarking for images and videos. We put emphasis on high robustness and security as well as decreased complexity. Our previous works have shown that the geometric structure of images and videos is a suitable embedding domain for watermark information. To describe the geometric structure, detection or segmentation methods are used, which...
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...
