4 of 32 A Note About Grey Levels So far when we have spoken about image grey level values we have said they are in the range [0, 255] – Where 0 is black and 255 is white There is no reason why we have to use this range – The range [0, 255] stems from display technologes For many of the image processing operations in this lecture grey levels are assumed to be given in the range [0. 0, 1. 0]

5 of 32 What Is Image Enhancement? Image enhancement is the process of making images more useful The reasons for doing this include: – Highlighting interesting detail in images – Removing noise from images – Making images more visually appealing
