This code applies local histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The window size may be changed, however, the window shift is pixel by pixel. The output is definitely a better contrast image as compared to the input but checkerboard effect is evident.
