RESEARCHERS from Purdue University have developed two new techniques for computer-vision technology, which mimic how humans perceive 3D shapes.

heat mappingHumans are capable of instantly recognising objects even if they are twisted or bent. Now, machines could possess the same capability with techniques called heat mapping and heat distribution.

Both techniques apply mathematical methods and build on the basic physics and mathematical equations related to how heat diffuses over surfaces. They draw on Albert Einstein’s contributions to an understanding of diffusion, and Fourier’s law, which is used to derive heat equation.

As heat diffuses over a surface it follows and captures the precise contours of a shape. The system takes advantage of this “intelligence of heat,” simulating heat flowing from one point to another and in the process characterizing the shape of an object.
