| Abstract: |
A variety of approaches have been proposed in the literature for Region Of Interest (ROI) estimation. In most of them the definition of ROI is highly subjective, i.e., lacks scientific evidence in supporting the claim that the areas defined as ROIs are indeed regions of interest for the most of human beings. In this paper we attempt to model ROIs as the visually attended areas indicated by a saliency map in order to lower as much as possible the subjectivity in selecting ROIs. For evaluation purposes, in terms of perceived visual quality and video compression improvement, a ROI-based video compression setup was followed. Extended experiments concerning both MPEG-1 as well as low bit-rate MPEG-4 video encoding were conducted showing significant improvement in video compression efficiency without perceived deterioration in visual quality. |
