Adaptive edge image enhancement based on maximum fuzzy entropy

Based on the maximum fuzzy entropy principle,the edge image with low contrast is optimally classified into two classes adaptively,under the condition of probability partition and fuzzy partition. The optimal threshold is used as the classified threshold value, and a local parametric gray-level transformation is applied to the obtained classes. By means of two parameters representing,the homogeneity of the regions in edge image is improved. The excellent performance of the proposed technique is exercisable through simulation results on a set of test images. It is shown how the extracted and enhanced edges provide an efficient edge-representation of images.
