摘要 针对MRI影像经常出现的正常组织和病态组织之间对比度不清的问题,文中采取基于小波变换的非线性的图像增强算法。实验结果表明,此增强方法能够在增强图像微小细节的同时避免噪声过增大,使结果图像具有很好的视觉效果。因此本文方法有效而实用。 Aimed at the unclear contrast problem between normal organization and morbid organization of the MRI, we adapted an enhanced algorithm of image, which based on wavelet transformation and nonlinear. Experiment of the method demonstrates that the algorithm avoids over-enhancement of noise while enhancing trivial image details, which have good visual effect. Thus, the method presented is practical and effective.
