The lower bound of human sketching ability

Speaking of adding more pictures to this blog, here are a couple of choice figures from a computer graphics paper I read recently [1] that had me giggling out loud at my computer screen at 2am. In it the authors describe a system for classifying sketches into groups automatically – but to do this you need to first have some sketches, made by humans, to classify. It turns out humans are not always the best at sketching [2]…

[2] The authors actually go on to analyze the problems with human sketches that lead to a “failure” of sketch classification systems – it’s a pretty neat paper, check it out.
