Abstract
A new medical image enhancement method aimed at optimizing contrast of image features while minimizing image noise is proposed in the paper based on contourlet transform using cycle spinning. We use the invariance contourlet to form the image representation and then deal with the contourlet coefficients with nonlinear transform as to enhance the details and meanwhile restrain the noise. The experiment results show that this method enhances the contrast of the image while avoiding over-enhancement of noise.
