An Adaptive Enhancement Algorithm of IR Image Based on Generalized Fuzzy Set Theory
Huixin Zhou · Journal of China Academy of Electronics and Information Technology · 2007
On the basis of generalized fuzzy set theory and local contrast enhancement, the paper presents an adaptive enhancement technique which deals with infrared image. The gray image is translated to correspondent general membership function by using atan mapping. The method can not only improve dynamic range, but also enhance the local contrast in the different gray levels with more image edges and details. Its efficiency and superiority are clarified by experiment.
