1. A method implemented using one or more processors, comprising:
determining a first probability distribution over a plurality of classes of a first biological object depicted in a first image captured at a first point in time;
determining one or more additional probability distributions over the plurality of classes of one or more candidate biological objects depicted in a second image, wherein the one or more candidate biological objects depicted in the second image potentially match the first biological object depicted in the first image, and wherein the second image is captured at a second point in time that differs from the first point in time;
predicting a probability distribution over the plurality of classes of the first biological object at the second point in time based at least in part on the probability distribution over the plurality of classes of the first biological object; and
comparing the predicted probability distribution to the one or more additional probability distributions of the one or more candidate biological objects depicted in the second image to match a given biological object of the one or more candidate biological objects depicted in the second image to the first biological object depicted in the first image.
