HSV-domain Enhancement of High-contrast Images - Power Laws and Unsharp Masking for Bounded and Circular Signals

Abstract

We present techniques for performing luminance mapping and unsharp-masking-like processing on digital images; they are specifically designed for their application on bounded and on circular signals. We study the effect of gamma correction on contrast and develop an adaptive technique for luminance and contrast correction. We use the proposed tools for the enhancement of high contrast color images.
