An attention based spatial adaptation scheme for H.264 videos on mobiles
When browsing videos in mobile devices, people often feel that resolution greatly affects their perceptual experience in the limited screen size. In this paper, an attention based spatial video adaptation scheme is proposed to overcome display constraints by producing the region of interest. According to the size of the target display, we automatically detect and crop the informative region in each frame to generate a smooth sequence. To avoid costly fully encoding operations, we employ a set of transcoding techniques based on the H.264 standard. Experimental results show that this approach not only improves the perceptual quality but also saves the bandwidth and computation, especially for the videos which are not well edited.
