Systems and methods for identifying and labeling objects in images using an index

A method by a computing system for automatically identifying and labeling objects in images using an index, the method comprising:

• accessing a plurality of first video frames of a first video captured at a first physical location;
• identifying a plurality of first objects from the plurality of first video frames;
• generating a plurality of first composite vectors for the plurality of first objects;
• storing the plurality of first composite vectors in an index;
• accessing a plurality of second video frames of a second video captured at a second physical location;
• identifying a plurality of second objects from the plurality of second video frames;
• generating a plurality of second composite vectors for the plurality of second objects;
• determining, using the index and the plurality of second composite vectors for the plurality of second objects, a plurality of similar objects;
• and
• displaying images of one or more of the plurality of similar objects in a graphical user interface;
• wherein the plurality of first composite vectors and the plurality of second composite vectors are linear combinations of a plurality of vectors generated for each of the plurality of first and second objects.

One or more computer-readable non-transitory storage media embodying instructions that, when executed by a processor, cause the processor to perform operations comprising:

• access a plurality of first video frames of a first video captured at a first physical location;
• identify a plurality of first objects from the plurality of first video frames;
• generate a plurality of first composite vectors for the plurality of first objects;
• store the plurality of first composite vectors in an index;
• access a plurality of second video frames of a second video captured at a second physical location;
• identify a plurality of second objects from the plurality of second video frames;
• generate a plurality of second composite vectors for the plurality of second objects;
• determine, using the index and the plurality of second composite vectors for the plurality of second objects, a plurality of similar objects;
• and
• display images of one or more of the plurality of similar objects in a graphical user interface;
• wherein the plurality of first composite vectors and the plurality of second composite vectors are linear combinations of a plurality of vectors generated for each of the plurality of first and second objects.
