Embodiments of the present invention are directed to a method and apparatus for probabilistic image analysis. In one embodiment, an image is normalized and filtered. A determination is made regarding the likelihood of the image randomly matching characteristics of the reference image. If the likelihood is smaller than a threshold, the system determines that the image and the reference image match. In one embodiment, the likelihood is determined by using patches of skin in the images. In one embodiment, the likelihood is derived from the coherence of the optical flow computed between the two images. In one embodiment, the image is partitioned into a plurality of pixel regions. A pixel region in one image is mapped to a best-fit region in the other image. A neighbor region of the pixel region is mapped to a best-fit pixel region in the other image . The positional relationship between the pixel region and its neighbor is compared with the positional relationship between the two best-fit pixel regions. |
