Τίτλος: | Biologically inspired region of interest selection for low bit-rate video coding | Συγγραφείς: | Tsapatsoulis, Nicolas Pattichis, Constantinos S. Rapantzikos, Konstantinos |
Major Field of Science: | Engineering and Technology | Field Category: | Electrical Engineering - Electronic Engineering - Information Engineering | Λέξεις-κλειδιά: | Image processing;Imaging systems;Visual communication | Ημερομηνία Έκδοσης: | 2007 | Πηγή: | 14th IEEE international conference on image processing, ICIP, 16-19 September 2007, San Antonio, TX | Περίληψη: | A variety of approaches have been proposed in the literature for region-of-interest (ROI) estimation. In most of them the ROI definition is highly subjective, i.e., lacks scientific evidence in supporting the claim that the areas defined as ROIs are indeed perceptually interesting. 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 of selection. For evaluation purposes we follow a ROI-based video compression setup and present comparisons with state-of-the-art algorithms in terms of perceived visual quality and video compression improvement. 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 | URI: | https://hdl.handle.net/20.500.14279/2336 | DOI: | 10.1109/ICIP.2007.4379314 | Rights: | © IEEE | Type: | Conference Papers | Affiliation: | National Technical University Of Athens University of Cyprus |
