Object-Backgpound Classification Using A New Definition Of Entropy

The definition of Shannon's entropy in the context of information theory ,is critically examined and some of its applications to image processing problems are reviewed. A new definition of classical entropy based on the expo­ nential behavior of information -gain is proposed along-' with its justification. The concept is then extended to fuzzy sets for defining a nonprobabilistic entropy and to gray tone image for defining its conditional entropy.
