基于二进小波变换的磁共振图像增强算法应用研究

摘要

在结合磁共振图像特点的基础上对二进小波变换的图像增强方法进行研究和改进,并应用到磁共振图像的对比度增强实验中.实验结果表明,改进后的算法比原算法有更好的增强效果,在增强对比度和抑制噪声两方面都取得了较好的效果.%According to the characteristics of MRI, an algorihm based on the dyadic wavelet tmsform for the image enhancement is researched and modified and used in the experiment of the enhancement of MRI. The experiments on the clinical images show that the modified algorithm has a better result compared with the original algorithm. The algorithm can achieve an excellent balance between the enhancement of subtle image detail and the avoid of noise amplification.
