1. A computerized method of image analysis comprising: a) receiving first image data for a plurality of first video frames representing a first scene, wherein (i) each first video frame comprises a plurality of image regions and (ii) a first object is present in an image region of at least one first video frame; b) receiving second image data for a plurality of second video frames representing a second scene, wherein (i) each second video frame comprises a plurality of image regions and (ii) a second object is present in an image region of at least one second video frame; and c) determining a relationship between first and second image regions of the plurality of image regions of the first and second video frames based on a probabilistic correlation between occurrences of the first object being present in the first image region and occurrences of the second object being present in the second image region.
