摘要：
In this paper, an image enhancement algorithm based on Contourlet transform is exhibited. The feasibility of the enhancement algorithm is verified through various pyramid and directional wavelet filter combinations. The enhanced images are evaluated by both the subjective and objective approaches. It provides us an alternative method to enhance the image contrast.
