A Novel Contrast Enhancement Technique on Palm Bone Images
Algorithms, 2014 Contrast enhancement plays a fundamental role in image processing. Many histogram-based techniques are widely used for contrast enhancement of given images, due to their simple function and effectiveness. However, the conventional histogram equalization (

HEBS: Histogram Equalization for Backlight Scaling [PDF]
Design, Automation and Test in Europe, 2005 In this paper, a method is proposed for finding a pixel transformation function that maximizes backlight dimming while maintaining a pre-specified image distortion level for a liquid crystal display. This is achieved by finding a pixel transformation function, which maps the original image histogram to a new histogram with lower dynamic range. Next the
