Dear All,
When we write imshow(a,[]) the [] scales the whole image by how much. I tried to divide by 255 but it didn't give the same results as putting the []!
Regards,

Doing [] takes the min of the image and puts it at 0 (black) and the max of the image and puts it at 255 (white). So let's say your image went from 60 to 130. Using [] would map 60 down to 0, and map 130 up to 255, and everything else would be linearly scaled in between.
