1. A computer-implemented method of detecting and tracking objects of interest, comprising:
obtaining, by a processor, stereo image frames from one or more image capturing devices, wherein each image capturing device is associated with a zone;
identifying, by the processor, one or more objects of interest within one or more of the frames, each of the identified objects described by one or more properties;
for each identified object:
determining, by the processor, whether the one or more properties satisfy a specified condition defined by one or more predicate operators; and
determining, by the processor, a position of the identified object based on one or more of i) the corresponding frames and ii) each zone of the one or more corresponding image capturing devices;
comparing, by the processor for each identified object having properties determined to satisfy the specified condition, the determined object one or more existing tracks, each existing track associated with a previously-tracked object of interest, the comparing based at least in part on one or both of the determined position of the identified object and the zone of the corresponding image capturing device;
for each compared object matching an existing track, adding, by the processor to the corresponding existing track, information about the matching object, including one or more of the determined position and the determined zone corresponding to the matching object; and
for each compared object not matching an existing track, creating and storing, by the processor, a track corresponding to the not matching object.
