The amount by which the image deviates from the template image is used as a measure of the acceptability of the image. Portions of the image at or near edges in the images may be automatically excluded from this test. Another test which includes the edge portions excluded from the first test may be performed to ensure that all portions of the image are inspected. For example, this other test may include ensuring that the correct number of edge pixels are present in the image as a whole.Other References
