  • Abstract
    Bit-depth expansion is important for displaying a low bit-depth image in a high bit-depth monitor. Existing methods tend to give disturbing contouring or blurring artifacts. In this paper, we propose a novel, simple and efficient adaptive method to increase bit-depth taking advantage of the existing techniques to give superior image quality.
