提出了一种基于Contourlet变换的图像增强算法。通过各种金字塔和方向小波滤波器组合验证了增强算法的可行性。通过主观和客观两种方法对增强后的图像进行评价。它为我们提供了一种增强图像对比度的替代方法。
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.
