Researchers developing a new machine-vision technique tested their method on certain complex shapes, including the human form or a centaur – a mythical half-human, half-horse creature. The heat mapping allows a computer to recognize the objects no matter how the figures are bent or twisted and is able to ignore “noise” introduced by imperfect laser scanning or other erroneous data. (Purdue University image/Karthik Ramani and Yi Fang)
