1. A method for determining if a first image and a second image are correlated images, the method comprising: partitioning a first image, comprising a plurality of pixels, into a plurality of corresponding pixel partitions, each of the plurality of pixel partitions comprising a predetermined number of pixels; partitioning a second image, comprising a plurality of pixels, into a plurality of corresponding pixel partitions, each of the plurality of pixel partitions comprising a predetermined number of pixels; calculating an average luminance value for each of the plurality of pixel partitions of the first image; calculating an average luminance value for each of the plurality of pixel partitions of the second image; determining if each of the plurality of pixel partitions of the first image is correlated with each of the corresponding plurality of pixel partitions of the second image; calculating a percentage of correlated pixel partitions of the plurality of pixel partitions of the first image and the corresponding plurality of pixel partitions of the second image; and determining that the first image and the second image are correlated images if the percentage of correlated pixel partitions exceeds a predetermined pixel partition correlation threshold.
