最大类间方差算法在运动检测系统中的应用

Application of Otsu method in motion detection system

为满足系统对实时性的要求,采用Altera公司的CycloneⅡ系列的FPGA实现最大类间方差算法。采用Verilog语言对算法实现建模,并在QuartusⅡ平台进行了仿真验证。实验结果表明,该设计能够快速有效地得到阈值,并能有效保护模糊目标的作用。

To meet the requirements of real-time systems, an implementation on FPGA of Ahera＇s Cyclone Ⅱ series for the BCVC （ Between Class Variance Computation） of Otsu＇s method was presented. It used Verilog language to model and simulate in Quartus Ⅱ platform. The experimental results show that the design can obtain threshold quickly and effectively, and can effectively protect the fuzzy goals.
