Amrita Mazumdar, Brandon Haynes, Magdalena Balazinska, Luis Ceze, Alvin Cheung, Mark Oskin
2019 arXiv   pre-print
In this paper, we propose Vignette, a compression technique and storage manager for perception-based video compression.  ...  Vignette's compression technique uses a neural network to predict saliency information used during transcoding, and its storage manager integrates perceptual information into the video storage system to  ...  Custom storage for perceptual data. Vignette's storage manager efficiently stores and manages perceptually compressed videos and is integrated in a modern video processing database system.  ...
