For the sensitivity to noise of some image enhancemext methods,an adaptive image enhancement algorithm is proposed.Using the basic principle of the original method,the parameters of the algorithm is adaptively generated according to the human visual properties.Firstly,the proposed algorithm can keep the original advantages such as easy realization and quick calculation.Secondly,it plays a certain part in restraining noise.Finally,it can enhance and reserve the detail information.By comparing with other image enhancement algorithms,the proposed algorithm can get parameters of algorithm automaticly.Besides the easy realization of original method,the new algorithm also can improve the performance in restraining noise.At the same time,it can be used to enhance color image.
