摘要： A plurality of images, including a first image and a second image having a higher resolution than the first image, are aligned by generating an oversampled cross correlation image that corresponds to relative displacements of the first and second images, and, based on the oversampled cross correlation image, determining an offset value that corresponds to a misalignment of the first and second images. The first and second images are aligned to a precision greater than the resolution of the first image, based on the determined offset value. Enhanced results are achieved by performing another iteration of generating an oversampled cross correlation image and determining an offset value for the first and second images. Generating the oversampled cross correlation image may involve generating a cross correlation image that corresponds to relative displacements of the first and second images, and oversampling the cross correlation image to generate the oversampled cross correlation image.
摘要翻译：通过产生对应于第一和第二图像的相对位移的过采样互相关图像，并且基于过采样交叉，对准包括具有比第一图像更高分辨率的第一图像和第二图像的多个图像相关图像，确定对应于第一和第二图像的未对准的偏移值。基于所确定的偏移值，将第一和第二图像对准到大于第一图像的分辨率的精度。通过执行产生过采样互相关图像的另一次迭代并确定第一和第二图像的偏移值来实现增强的结果。产生过采样互相关图像可以涉及产生对应于第一和第二图像的相对位移的互相关图像，并且对互相关图像进行过采样以生成过采样互相关图像。
