| Abstract: | In this paper,an image enhancement algorithm based on wavelet transform is proposed.According to wavelet transform s local time-frequency capacity and directional characteristics,the high frequency sub-bands coefficients divided into wavelet trees.Operated the coefficients of wavelet tree,the whole image contrast is enhanced.The algorithm is implemented in Microsoft Visual C++ programming language.Simulation results show that the algorithm can provide better visual quality,and it is an effective image enhan... |
