摘要:
A quantitative measure of image enhancement is presented. It is based on the concept of ‘available information’ which is also defined here. We then apply these concepts to representative forms of image enhancement. The benefits derived from simple enlargement are put on a quantitative basis, as is the degradation due to excessive enlargement. It is shown that noise reducing techniques such as low-pass filtering do enhance an image, up to a point. Beyond this they degrade the image.
