Abstract
A method for realistic stitching and showing image blocks of an electronically recorded multipart image wherein relative positional offset values of the image blocks recorded with overlap are determined in a co-ordinate system in directions x and y and stored in matrix format, and the image blocks to be presented are stitched together on the basis of the stored values the method comprising: subdividing the overlaps of the individual image blocks into smaller regions with fixed relative positions; picking up at least one region most useful for the determination of the stitching; determining the offset goodness value based on the similarity of pattern of the image blocks; stitching the blocks of the image so that first the two image blocks characterized by the best offset goodness values are stitched together and the two image blocks characterized by the worst offset goodness values are stitched together last, whereas only the co-ordinates of the images figuring in a table are modified in the course of the stitching process; and distributing the errors produced by the stitching process over several image blocks.
