Yang [IEEE Conference on Field Programmable Technology, Singapore, Dec. 2005] abstract. This paper describes the design and implementation of hardware architectures for posture analysis. Posture analysis is an active research area in computer vision. It can be used in providing health-care solutions, such as monitoring home care patients. We report four contributions in this paper: (a) requirements for a posture analysis system with hardware support; (b) a work(c) various architectures and their implementation based on a high-level hardware design approach; (d) performance evaluation for our derived designs. For instance our best design, which targets a Xilinx XC2V6000 FPGA at 90.2MHz, is able to perform posture analysis at a rate of 1164 frames per second with frame size of 320x240 pixels, or 220 frames per second for DVD quality of 720x576 pixels per frame. This represents a 145-fold speedup over a software version running on a 3Ghz Pentium-4 computer.
