摘要
利用传统的运动检测算法评价方法的原理,提出一种适用于背景减法的运动检测算法的性能评价方法。该方法基于理想的检测对象可以获得(可以通过人工方法获得,或通过某种可靠的途径获得)。现实现了W4和W4+算法的C++代码,并用提出的评价方法对其进行评价,针对风动树叶背景的视频图像,识别运动物体。实验结果表明,该评价方法可以量化地表明运动检测算法检测效果的优劣。
Using the principle of the traditional perfonnance evaluation methods of motion detection algorithm, this paper presents a method for performance evaluation of motion detection algorithm based on background subtraction. This method is based on the following truth： the ideal detection object（Ground-Truth） can be gotten（produced by manual or some reliable procedures）. This paper implements the W4 and W4 ＋ algorithms with C ＋＋ and uses the presented evaluation method to evaluate W4 and W4 ＋ algorithms. Experimental results show that this method works well to prove that the algorithm has better detection results.
