dc.description.abstractThis paper presents different methods of retargeting 4K resolution videos for the smaller resolutions of mobile devices. Several methods are investigated using image cropping based on visual attention maps with removal of temporal jitter. Visual comparison between video sequences obtained from the retargeting methods is presented and evaluated through subjective testing. Based on subjective scores, the proposed algorithm shows the best performance for 480p target resolution.eng
