| Abstract: | We propose a fast video transcoding technique based onRegion-of-Interest (ROI) determination. The ROIs areidentified using the properties of the Human Visual System(HVS), applied in the compressed domain. We use the edge,motion and spatial frequency content of the video frame as theparameters in identifying perceptually important regions incompressed domain [9]. The TM5 rate-control of the videotranscoder is modified to assign relatively more bits to theROIs, thereby providing better quality to the areas that arelikely to attract the viewer’s attention. The ROI determinationin compressed domain has been modified to give more robustresults. Our algorithm achieves a speed-up of 15-20 times ascompared to similar algorithms in pixel domain while givingcomparable results. This computation is only around 8% of thetotal transcoder complexity. | ||
