Systems and methods for navigating a host vehicle are disclosed. In one implementation at least one processor is programmed to receive a first signature encoding generated by a first trained model implemented by a first processor associated with a first camera; receive a second signature encoding generated by a second trained model implemented by a second processor associated with a second camera; input the first signature encoding and the second signature encoding into a third trained model, wherein the third trained model is configured to determine a location of an object represented in the first image and the second image; and receive an indicator of the location of the object determined by the third trained model.
