Abstract An automatic clipping method for the scanned object with irregular edges includes such steps as setting up a pattern in a fixed style on the bottom plate of the top cover on scanner, using it as the reference coordinate for clipping, pre-scanning the pattern when the scanner is first installed, analyzing the coordinate of the pattern, average RGB values and variables, creating a database of bottom plate styles, sequentially comparing the data in the database with the RGB chromatic differene of pre-scanned image, judging the position of object, and treating the background of the scanned object's edge with transparent colour to obtain needed image.
