System and method for periodic pattern detection for motion compensated interpolation

摘要

A method for detecting a pattern in an image includes defining a set of pixel values in an image using a window and calculating a Fourier transform of the pixel values. In one embodiment, the Fourier transform of the pixel values forms a spectrum. The method further comprises analyzing the spectrum of the Fourier transform to find a peak and analyzing the peak to determine whether the peak is indicative of the presence of a pattern in the image.
