Learning Better Lossless Compression Using Lossy Compression
Fabian Mentzer, Luc Van Gool, Michael Tschannen
We leverage the powerful lossy image compression algorithm BPG to build a lossless image compression system. Specifically, the original image is first decomposed into the lossy rec…

Learning for Video Compression with Hierarchical Quality and Recurrent Enhancement
Ren Yang, Fabian Mentzer, Luc Van Gool +1
In this paper, we propose a Hierarchical Learned Video Compression (HLVC) method with three hierarchical quality layers and a recurrent enhancement network. The frames in the first…

Practical Full Resolution Learned Lossless Image Compression
Fabian Mentzer, Eirikur Agustsson, Michael Tschannen +2
We propose the first practical learned lossless image compression system, L3C, and show that it outperforms the popular engineered codecs, PNG, WebP and JPEG 2000. At the core of o…
