Abstract
A method and device for image registration, and a computer program product. The method includes performing, based on a reference image, a first registration of an image to be registered, including determining a first offset between predetermined areas on the image and the reference image, and moving all bright spots on the image based on the first offset; performing, based on the reference image, a second registration with respect to the first registered image, including merging the first registered image and the reference image, calculating the offset of all overlapped bright spots in the predetermined area on the merged image to determine a second offset, two or more bright spots distanced by less than a predetermined number of pixels being one overlapped bright spot, and moving, on the basis of the second offset, all bright spots on the first registered image, thus implementing the registration of the image.
