  • Abstract
    In this paper, we propose Adaptive Histogram Equalization (AHE) based contrast enhancement algorithm. Most histogram-based contrast enhancement methods have problems such as excessive contrast enhancement, unnatural output images, and the loss of visual information. The proposed method manipulates the slope of the input of the Probability Density Function (PDF) histogram. Our method adaptively enhances the contrast of the input image and shows good simulation results compared with conventional methods.
