基于Contourlet变换的MRI医学图像增强

On MRI Medical Image Enhancement Based on Contourlet Transform

利用Contourlet变换的多尺度、局部化、方向性等优点,提出一种基于Contourlet的MRI图像增强方法。实验结果表明,与传统的方法相比,该方法能够更有效地增强MRI图像的边缘细节特征,获得良好的效果。

Contourlet transform is a new kind of image representations which is of multi-resolution,local supporting and multi-direction.A new algorithm of the MRI image enhancement using Contourlet transform is proposed.Simulation experiments were carried out.The experiments show that the algorithm proposed gets good results and enhances the images details and texture compared to the traditional algorithm.
