Abstract

A target object captured by a first camera is identified in images captured by a second camera. A reference platoon comprising the target object and other objects is generated using first camera images. A reference group characterizing the objects in the reference platoon is generated by running a first set of trained classifiers over the reference platoon, the first set of trained classifiers trained to characterize objects captured by the first camera. Candidate platoons are generated using second camera images. Candidate groups characterizing objects in the candidate platoons are obtained by running an independently trained second set of classifiers over the candidate platoons, the second set characterizing objects captured by the second camera. Candidate groups are compared to the reference group, and a best matching candidate platoon is selected. The target object is identified in the selected candidate platoon based on the object's position in the reference platoon.
