Abstract:
A pattern detection apparatus inputs an image of an object including repetitive patterns, estimates a period of the repetitive patterns in the input object, and generates a reference image based on images divided by the estimated period. Then, the pattern detection apparatus compares the reference image and the image of the object, and detects the positions of individual patterns in the repetitive patterns based on the comparison result.
