| 摘 要： | 针对基于图像边界Hausdofff距离场的图像配准方法存在的问题，提出一种基于最近点拟引力场的图像配准方法：假定参考图像边界点形成最近点拟引力标量场,用浮动图像边界点在该引力场中受力的均值作为相似度函数．该方法弱化了浮动图像中多余边界的作用，提高了算法精度，降低了误配率，解决了浮动图像中存在多余边界情况下的配准问题．

| Abstract: | In order to overcome the disadvantages of the image registration method based on Hausdorff distance field of image edges, an image registration approach based on the nearest-point pseudo gravitation field is presented, in which the edge points of the reference image are assumed to generate a nearest-point pseudo gravitation field, and the average force loaded on the edge points of the floating image in the gravitation field is adopted as the similarity function. This approach reduces the effect of excess part of the floating image, improves the precision of image registration, and decreases the misregistration ratio. Thus, the registration of excess edges in the floating image is effectively solved. |
