Method of producing a transit graph
First Claim
1. A method of producing a transit graph of information relating to movements of a plurality of targets from a first of a plurality of locations to a second of the plurality of locations comprising:
- processing a plurality of target observations from a plurality of image capture devices to produce a primary track for a target, wherein the primary track includes an ordered sequence of observation events having similarities in their visual signatures;
processing the primary track to determine information relating to movement of a target from the first of the plurality of locations to the second of the plurality of locations; and
updating the information in the transit graph based on a refined track determined by decomposing the primary track using the information in the transit graph.

Abstract
One embodiment of a method of producing a transit graph of a priori information relating to movements of a plurality of targets from a first of a plurality of targets locations to a second of the plurality of locations can be broadly summarized by the following steps: processing a plurality of target observations from a plurality of image capture devices to produce at least one primary track for at least one target, wherein each primary track includes ordered sequences of observation events having similarities in their visual signatures; and processing the at least one primary track to determine a priori information relating to movement of a target from a first of a plurality of locations to a second of the plurality of locations. Other methods and systems are also provided.

12. An apparatus for producing a transit graph of information relating to movements of a plurality of targets from a first of a plurality of locations to a second of the plurality of locations comprising:
-
a plurality of image capture devices; and a processor to process a plurality of target observations from the image capture devices to produce a primary track, to process the primary track to produce information relating to movement of a target from a first to a second location, and to update the information in the transit graph based on a refined track determined by decomposing the primary track using the information in the transit graph, wherein the primary track includes an ordered sequence of observation events having similarities in their visual signatures.
