1. A computer-implemented method for distinguishing objects in a scene, comprising:
distinguishing, based on blob variation information of a height map, between at least a first object and a second object in each of a plurality of images captured in an area;
determining, based on one or more properties associated with the first object and the second object, whether the second object is associated with the first object; and
upon determining that the second object is associated with the first object:
classifying the first object as an individual; and
classifying the second object as a large object in relation to the individual.
