TO provide Contrast Limited Adaptive Histogram Equalization
image_ret=cv_clahe(image,clipLimit,titleGridSize)
Input Image
It takes integer/float value and clips the histogram from using this value
It takes list as input example:[5,5]: Tilegridsize defines the size of tile/window size
Image returned after clahe operation
Contrast Limited Adaptive Histogram Equalization
Here the Image is divided into small blocks/tiles Then each of this block are histogram equalized as usual
