摘要：
A method includes detecting vertical edge pixels in an image and analyzing the detected vertical edge pixels by horizontal location in the image to detect a spatial periodicity in the detected vertical edge pixels. The method further includes detecting horizontal edge pixels in the image, and analyzing the detected horizontal edge pixels by vertical location in the image to detect a spatial periodicity in the detected horizontal edge pixels.
