Original Abstract Submitted
Improved image coding techniques for high-bit depth images includes deriving two or more separate lower-bit-depth main and extension images from one high-bit-depth source image, and then encoding them separately as lower-bit-depth images. At a decoder, the separate main and extension images are decoded, and then combined to create a single reconstructed source image. The improved techniques may use lossless or lossy codecs, and may provide some backward compatibility with legacy decoders.
