1. A computer implemented method of aligning scanned images, comprising:
- convolving a scanned image with a filter, the scanned image including at least a first pattern that the filter will convolve into a second pattern in a convolved image;
identifying the second pattern in the convolved image; and
aligning the scanned image according to a position of the second pattern in the convolved image.

Abstract
Systems and methods for aligning scanned images are provided. A pattern is included in the scanned image so that when the image is convolved with a filter, a recognizable pattern is generated in the convolved image. The scanned image may then be aligned according to the position of the recognizable pattern in the convolved image. The filter may also act to remove the portions of the scanned image that do not correspond to the pattern in the scanned image.

11. A computer program product that aligns scanned images, comprising:
-
computer code that convolves a scanned image with a filter, the scanned image including at least a first pattern that the filter will convolve into a second pattern in a convolved image; computer code that identifies the second pattern in the convolved image; and computer code that aligns the scanned image according to a position of the second pattern in the convolved image; and a computer readable medium that stores the computer codes. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
