Vision Chip

Japanese version is also available.

Concept

The aim of this project is to realize a high-speed real-time vision system by integrating photo detectors (PD) and digital processing elements (PE) on a VLSI chip. This architecture yields remarkably faster real-time visual processing when compared with conventional vision systems. We investigate this vision chip architecture from a whole system integration viewpoint; that is, we are not only developing full-custom VLSI chips but also algorithms, system software, and applications such as robotic systems.
