A New Method of Low Contrast Image Enhancement
一种新的低对比度图像增强的方法

A new method of low contrast image enhancement is presented based on PCNN and nonlinear extension in conjunction with characteristics of human visual consciousness in this paper. Approaches of local and whole contrast enhancement of image are discussed in detail. It is showed that the method not only ameliorates visual effect obviously but also has properties of smoothing image, enhancing image and self-adaptation through analysis and experiments.
