快速坐标变换方法及其在图像配准中的应用

Approach of Rapid Coordinate Transform and Application in Image Registration

图像的坐标变换在图像配准过程中具有重要作用。在分析传统坐标变换方法的基础上提出一种图像快速坐标变换方法，实验表明该方法可以较大地提高配准的计算速度而不影响配准精度，且具有一定的通用性，可用于图像处理的其他领域。

Coordinate transform of image plays an important role in the process of image registration. A rapid coordinate transform approach of the image is brought forward by analyzing the traditional approach and the experiment shows that the computing speed is comparatively enhanced without any impact on the precision of the registration. Besides, it is universal to some extent and available to other fields with respect to image processing.
