An Images Enhancement Algorithm Combined with Wavelet and Curvelet
Xiaowei Han · Journal of Engineering Graphics · 2009
Based on combinations of wavelet and curvelet transforms,a adaptive combined enhancement algorithm(ACEA) is proposed to solve the problems of the conventional method for image enhancement based on wavelet transform that the enhancement of edges,whose contrast is same but angles are different,is greatly different.The algorithm uses the wavelet transform to enhancement homogeneous areas and the curvelet transform to enhancement areas with edges.Experiment results show that the algorithm gets better cross entropy and CORR,and improves the effect of edge enhancement with good visual effect.
