Claim 14:
15. A system, comprising:
a memory that stores a first image containing a first object and a second image containing a second object, wherein the first object and the second object are included in a single object category; and
a processor that is connected to the memory, wherein the processor is configured to:
identify a region of the first image as a reference image according to selection criteria;
process, by a portion of a neural network model, the first image, the second image, and the reference image according to parameters of the neural network model to produce corresponding intermediate two-dimensional (2D) features;
map the 2D features produced for the reference image to the 2D features produced for the first image through the 2D features produced for the second image to generate predicted correspondence for the region;
compute a contrastive loss based on the predicted correspondence and the selection criteria for the region; and
update the parameters based on the contrastive loss.
