In recent years,the distribution characteristic of pixel intensity is proposed,which effectively absorbing the advantages of global and local image enhancement algorithm,avoiding over enhancement,noise amplification and other defects.However,the performance of the algorithm is heavily dependent on the selection of local artificial threshold.In this paper,by the Just Noticeable Difference(JND)curve from the human eye,dynamic thresholds with visual sense are generated.Then the image pixels are divided into different channels for statistical processing,in order to construct the mapping functions.Finally the enhanced image is a weighted fusion of different channels.The experimental results show that the proposed algorithm has better effect and adaptability.
