Method and device for establishing correspondence between objects in a multi-image source environment

A non-transitory memory storing one or more programs, which, when executed by one or more processors of a device, cause the device to:

• generate a set of candidate objects based at least in part on a set of image data, wherein the set of image data includes image data from a set of frames captured by each image source of a plurality of image sources;
• generate a set of visual signatures, wherein each of the visual signatures in the set of visual signatures characterizes a candidate object in the set of candidate objects;
• generate, based on the set of visual signatures, a correspondence matrix of similarity scores between each candidate object of each frame of each image source and candidate objects of each of the other frames of each of the other image sources;
• and
• transform at least two candidate objects in the set of candidate objects into a single object according to a determination that a similarity score from the correspondence matrix, between the at least two candidate objects, exceeds a threshold score.
