Patent attributes
A system and visitor recognition method receives a first image of a detected visitor at a first location, compares the image of the detected visitor to a prior visitor model including images of prior visitors to the first location or a second location. In some embodiments, when an image of the detected visitor matches the images of the prior visitor captured at a time differing from the capture time of the image of the detected visitor, the detected visitor is determined as unknown. In some embodiments, when the image of the detected visitor matches a group of images of a prior visitor at the second location, and the number of times the prior visitor was previously detected at the second location is above a second threshold, the detected visitor is determined as known, even if the detected visitor was not detected at the first location at least a threshold number of times.
