Patent ID: 6944343

Claim:
A method for analyzing a time sequence of images comprising: dividing a reference image based on its visual content into: (a) first spatially fixed areas of each image in said time sequence of images to analyze for detection by selecting in said reference image one or more detection cells collectively comprising a detection zone in which a statistically significant change in one or more predetermined features in said time sequence of images to be analyzed is expected to occur; and (b) second spatially fixed areas of each image in said time sequence of images to veto a detection of a statistically significant change in one or more predetermined features in said time sequence of images by selecting in said reference image one or more veto cells collectively comprising a veto zone in which any detection in said veto zone of a statistically significant change in one or more predetermined features in said time sequence of images is used to disable any detection of a statistically significant change in said one or more predetermined features in said time sequence of images in said detection zone.
