  • Systems and methods for performing region-based local contrast enhancement
    Patent number: 8885105
    Abstract: Local contrast enhancement comprises obtaining a first frame as a reference frame and a second frame as a current frame. The reference frame is partitioned into a plurality of reference regions, and a first color mapping function is derived for at least one of the reference regions in the reference frame according to the corresponding color distribution. The first color mapping function comprises, for at least one of a predetermined set of colors, a first source color value and a first contrast-enhanced color value. The current frame is partitioned into a plurality of regions, and a second color mapping function is derived for at least one of the regions in the current frame according to the first color mapping functions of at least two of the reference regions in the reference frame. The second color mapping function is applied to generate a contrast-enhanced frame.
