The networks are jointly trained through a differentiable codec proxy to minimize a given rate-distortion loss. This sandwich architecture not only improves the standard codec's performance on its intended content, but more importantly, adapts the codec to other types of image/video content and to other distortion measures. The sandwich learns to transmit ``neural code images'' that optimize and improve overall rate-distortion performance, with the improvements becoming significant especial","authors_text":"Berivan Isik, Danhang Tang, Hugues Hoppe, Jonathan Taylor, Onur G.
