Sandwiched Compression: Repurposing Standard Codecs with Neural Network Wrappers
Onur G. Guleryuz, Philip A. Chou, Berivan Isik +6
We propose sandwiching standard image and video codecs between pre- and post-processing neural networks. The networks are jointly trained through a differentiable codec proxy to mi…
