Development of an Image Enhancement Method and a GUI
Rima Deb,Dipali Sengupta,Rupasree Das,Subhankar Mahajan,Sanjoy Mitra 보안공학연구지원센터 2015 International Journal of Signal Processing, Image Vol.8 No.6
This article introduces a new adaptive local image enhancement method and a graphical user. The algorithm for image enhancement will correct contrast for some certain areas of an image which is based on edges contained in the image and some statistical properties; variance of the whole image and mean value of an image block. A contrast correction gain is chosen for each image tile based on statistical properties. The algorithm improves the visual quality of an image and also restricts noise amplification. The algorithm is tested with grayscale images and results are compared with histogram equalization and adaptive histogram equalization techniques by image quality metrics parameters.
