基于CamShift的手势跟踪算法的定点实现

Fixed-Point Implementation of Gesture Tracking Algorithm Based on CamShift

在OpenCV 1.0中CamShift浮点算法的基础上,对算法进行定点实现。介绍CamShift算法的基本原理,详细阐述对CamShift浮点程序定点化的方案、流程和具体方法。定点化结果表明,定点化后程序与原浮点程序偏差较小,满足跟踪性能的要求,可用于下一步的硬件实现。

Describes the fixed-point implementation of CamShift algorithm based on OpenCV 1.0. Intro- duces the basic principles of the CamShift algorithm, and elaborates the float-point to fixed- point program and flow of CamShift algorithm. The result of experimentation shows that the de- viation between the float-point and fixed-point is small, can meet the requirement of tracking application, and can be used to the hardware implementation of next step.
