A team of researchers from the National University of Singapore (NUS) has developed a novel microchip named EQSCALE that can capture visual details from video frames with extremely low power consumption. The video feature extractor uses 20 times less power than existing best-in-class chips, so it only requires a tiny battery. It could reduce the size of smart vision systems down to the millimetre range. For example, it can be powered continuously by a millimetre-sized solar cell without the need for battery replacement.
