METHOD AND DEVICE FOR ENCODING AN IMAGE, METHOD AND DEVICE FOR DECODING AN IMAGE

摘要

A method and a device for encoding and decoding High Dynamic Range (HDR) images and videos whose pixels are represented by high bit depth integers. In particular, a scalable compression scheme involving numerical representation and prediction of color information for the HDR enhancement layer given and LDR layer by generating color prediction information in response to a reconstructed LDR layer and a reconstructed HDR layer.
