I intend to correct the intensity in the images which arises due to the non uniformity in the illumination source.
As illustrated in the attched image, due to presence of inhomogeneity associated with the illumination source, the intensity is maximum at left and right side, however it is low on top and bottom. Now I intend to have uniform intensity through out. Is there any way out to achieve this ??
I tried with the normalize option e.g., But I am not succesful ..
normalize ( image data, 'range')
