Abstract:
A highly accurate reproduction of visual intensity and contrast rather than the conventional 8-bit color depth is more and more used, motivating the development of an enhanced dynamic range called high bit-depth. A method for encoding a first, low bit-depth image of M bit RGB pixels and a second, high bit-depth video image of N bit RGB pixels, M
