摘要
提出一种新的用于交通流量检测的自适应背景初始化算法,根据运动目标数目自适应地确定所需帧数,通过循环逐步缩小目标像素区域。解决了用固定帧数来提取背景时帧数确定的问题。实验表明,该算法实时性较高,简单有效。
An adaptive background initialization algorithm used in vehicle flow measuring system is proposed in this paper, It can determine frame numbers with stepwise reducing target region by cycle according to the number of moving objects, and solve the problem to verify frame by the fixed numbers when extracting the background. Emulation results show this algorithm is simple and real-time.
