Abstract
The present invention relates to a method and a system for aligning at least one part of a second digital image with at least one part of a first digital image comprising: dividing the at least one part of the first digital image into a plurality of tiles t_fi; dividing the at least one part of the second digital image into a plurality of tiles t_si; creating a plurality of correlation images fci; determining the position of a global maximum correlation value p_ν′ for each of the plurality of correlation images fci_ν′; calculating a plurality of first offset vectors fov, the offset vector fov_ν″ representing the offset between the tile t_siν″ and the corresponding tile t_fiν″; and aligning the at least one part of the second digital image with the at least one part of the first digital image by applying the corresponding first offset vectors fov.
