Claim 17:
18. A device arranged to track an object across a set of image frames, the device comprising a processor arranged to:
input a first frame of the set of image frames into a first neural network, the first neural network comprising at least one convolutional layer and at least one fully-connected layer;
receive a first output from the first neural network representative of a first map value associated with the first frame and a region of interest in the first frame that comprises the object;
determine a weight value based at least in part on the first map value and the region of interest;
input a second frame of the set of image frames into the first neural network;
receive a second output from the first neural network representative of a second map value associated with the second frame;
input the second map value and the weight value into a second neural network; and
receive a third output from the second neural network identifying a region of interest in the second frame as matching the region of interest in the first frame; and
determine a location of the object in the second frame based at least in part on the third output.
