An Image Enhancement Arithmetic Research Based on Fuzzy Set and Histogram

This paper focuses on discussing a Fuzzy Enhancement Arithmetic Based on Histogram for image enhancement using fuzzy theory and histogram. With the statistic characters of histogram and flexibility of fuzzy set, this arithmetic can enhance the effect of some interested image-area freely, compared with some enhancement arithmetic using histogram alone or using selected threshold value difficultly. The paper proposes the corresponding theories and detailed process to carry out the arithmetic, and analyzes how to select the involved parameters xc, r and Fe in it. After that, the paper also gives an example for the application of the arithmetic.
