    Abstract: Novel methods and systems for image processing and gamut mapping are disclosed, where image parameters in a first color space are transformed into parameters in a second color space. In one example, the gamut mapping system processes the image parameters in a parametrized space using substantially rectangular spectral functions. In another example, the gamut mapping system processes the image parameters in a parametrized space using smooth spectral functions. The smooth spectral functions may include a linear combination of functions, including at least a cosine square function. Image parameters may include an intensity parameter, a center wavelength parameter, and a saturation parameter.

    Abstract: Coding syntaxes in compliance with same or different VDR specifications may be signaled by upstream coding devices such as VDR encoders to downstream coding devices such as VDR decoders in a common vehicle in the form of RPU data units. VDR coding operations and operational parameters may be specified as sequence level, frame level, or partition level syntax elements in a coding syntax. Syntax elements in a coding syntax may be coded directly in one or more current RPU data units under a current RPU ID, predicted from other partitions/segments/ranges previously sent with the same current RPU ID, or predicted from other frame level or sequence level syntax elements previously sent with a previous RPU ID. A downstream device may perform decoding operations on multi-layered input image data based on received coding syntaxes to construct VDR images.
