Moment calculation method for digital vision chip

Recently, an interesting general-purpose digital vision chip has been realized by integrating a photodetector (PD) and a processing element (PE) directly connected for each pixel on a single chip. This paper proposes bit plane (BP) feature decomposition as a realization of the idea of feature calculation that is suited to a massively parallel processing structure integrated on the digital vision chip. Moment calculation based on the method is discussed. An evaluation of the digital vision chip using the proposed calculation method is presented, and its effectiveness is demonstrated. © 2002 Wiley Periodicals, Inc.
