I know facial recognition algorithms and human facial recognition work wildly differently. However, the two faces are similar enough that several months of training, with some ability to choose perspective, isn't sufficient for my oldest to be able to distinguish the twins. In order for me to be confident which of my twins I'm looking at, I need a view at least 30 degrees off center from the left side to get a clear enough view of the subtle difference in the shape of the top of the left ear. I'm not confident a one-shot algorithm can reliably distinguish them without also sometimes believing one of them is two different people.
