1. A computer-implemented method comprising:
obtaining first data comprising a first collection of coordinate data representing a position, or positions, of a first group of one or more objects detected in a first frame of a scene;
obtaining second data comprising a second collection of coordinate data representing a position, or positions, of a second group of one or more objects detected in a second frame of the scene, wherein the second frame represents a different view of the scene than the first frame; and
determining whether any of the first group of objects correspond to any of the second group of objects in the scene based on the first collection of coordinate data and the second collection of coordinate data,
wherein the first frame and the second frame are obtained from image data captured from a single camera position,
wherein determining whether any of the first group of objects correspond to any of the second group of objects comprises:
transforming at least one of the first collection of coordinate data and the second collection of coordinate data such that the first collection of coordinate data and the second collection of coordinate data correspond to a common coordinate system; and
determining differences between the first collection of coordinate data and the second collection of coordinate data according to the common coordinate system.
