Abstract
Techniques are disclosed for correcting noisy clamped image sources while preserving original luma, chroma, or other channel value. A computing device can receive an image that has a plurality of pixels associated with respective channel values. The computing device can then determine a region of the image for correction and generate a histogram of the respective channel values in the region. Based on the histogram, the computing device can generate a corrected histogram of corrected channel values. The computing device can then denoise the corrected channel values.
