is it possible to recognise the subject of a simple childlike drawing from a scan or photograph?

Question

I am developing a study for child psychology and would need to analyze thousands of children's drawings, I would like to automate where possible through edge tracing, etc. to guess the content of the picture comparing it to a library of objects... sun, houses, trees, dogs, etc. is it possible?

Answer 1

Visual indeterminacy is a perceptual sensation that occurs when a viewer is displayed with a meaningful visual stimulus that refuses easy or immediate identification. Here are two stills from The Cabinet of Dr. Caligari showing (left) the moment of non-recognition and (right) the moment of recognition just after 5 s later. 

If you can do this (detexify.kirelabs.org/classify.html), you certainly can classify a good enough drawing as either house, person, tree, flower, sun or car.
