Abstract
A method includes: accessing a first frame; detecting a first object in the first frame; extracting a first location and a first set of features of the first object; transforming the first set of features into a first set of hash values; storing the first set of hash values in a first object container in a set of object containers; accessing a second frame; detecting a second object in the second frame; extracting a second location and a second set of features of the second object; transforming the second set of features into a second set of hash values; querying the set of object containers for the second set of hash values; and in response to a second object container containing a threshold quantity of hash values in the second set of hash values, identifying the second object as previously detected and represented by the second object container.
