I am not a computer vision specialist, but I wanted to add an anecdote from years of parenting. One thing that amazed me about babies was how early they understand line drawings. Long before a baby can talk, it knows what a dog is (and can imitate a dog sound), and can also identify a dog in a photo, in a realistic drawing, and in a very simple line drawing. It seems so easy, but in reality those things all look so very, very different. And after 6ish months, babies have mastered that recognition.
