I have a very basic question. I understand that contrast enhancement is exaggerating the difference between the intensity of the adjacent structures and texture in an image is the repeating geometric patterns in an image. But what is exactly texture enhancement? Does enhancing contrast in an image automatically enhance texture also? Can someone explain this with an example. By looking at an image, how can one identify if the image needs contrast enhancement or texture enhancement? Or how does one identify, if an algorithm has done contrast enhancement or texture enhancement?
