基于边缘提取的医学图像配准方法

Image registration based on edge extraction

图像配准是图像分析和处理的基本问题，在医学影像、遥感遥测、计算机视觉等领域有着广泛的应用。基于边缘提取和利用Ｆｏｕｒｉｅｒ变换和Ｍｅｌｉｎ变换，本文提出了估计医学图像之间的配准参数的新方法。文中的计算机模拟结果表明，这种方法非常适合多模态医学影像处理。

Image registration is a fundamental problem in image analysis and processing, and is used in a wide variety of applications. An edge based method of the medical images registration was revealed by using the techniques of Fourier and Mellin transforms. The simulation results shown in this paper illustrated that the proposed method was very suitable for processing the multi modality medical images, such as X CT, MRI and PET.
