一种基于非下采样剪切波变换的医学图像配准方法
Medical image registration method based on non-subsampled shearlet transform
摘要
Abstract
The computational complexity of medical imaging and insufficient direction information are the drawbacks of classi-cal elastic registration methods.Based on the study for the problem,this paper proposed a new medical image registration algo-rithm based on non-subsampled shearlet transform(NSSTR).In the method,it used the privilege that shearlet could locate each scale,direction and position.Firstly,the algorithm used non-subsampled shearlet transform on medical image to obtain scale,di-rection of subband shear coefficient,then adopted different registration methods for high frequency and low frequency images respectively.Finally,the algorithm got changing grid and registration image.Experiments show that the new proposed method outperforms traditional methods in the aspect of registration precision and robustness.Especially the algorithm is with higher computational efficiency.关键词
