Harpreet Kaur, Neelofar Sohi · The International Journal of Engineering and Science · 2017
Image Enhancement aims at improving the visual quality of input image for a particular area.The criterion used by enhancement algorithms to enhance the image is; using histogram details of that image.This paper defines the various applications of histograms through which they help in the enhancement process.The paper also represents three basic histogram processing techniques-histogram sliding, histogram stretching, and histogram equalization, and how these techniques help in enhancement process, which factors effect these techniques.We examine subjectively the effect of these processing techniques.Comparative analysis of these techniques is also carried out.
