Abstract
Image encoding and decoding are described. An input HDR image that includes a base image and a ratio image may be stored using two or more color description profiles. One profile defines the encoding color space of the base image and the second profile defines the encoding color space of the HDR metadata which may be different than the color space of the base image.
