Hello friends,

I am working on retinal images and need to make them standard before processing, because some images are dark others are very light. So before processing I am doing the following:

gemiddeld=mean2(DOG)

standaard_afwyking=std2(DOG)

NormalizedArray = (DOG-gemiddeld) ./ standaard_afwyking;

NormalizedArray =((NormalizedArray + 3)./ 6).*255

figure,imshow(NormalizedArray);

This is not working, because the output is just a blank white image.How can I fix this?Hello friends,
