Past work in leveraging perceptual cues like saliency, i.e., regions where viewers focus their perceptual attention, reduces compressed video size while maintaining perceptual quality, but requires significant changes to video codecs and ignores the data management of this perceptual information.\n  In this paper, we propose Vignette, a compression technique and storage manager for perception-based video compression.
