| 摘 要： | 针对车辆检测中实时性、准确性以及自适应性很难兼顾的问题,提出了一种快速有效的车辆检测算法。该算法采用阈值判定背景区域和更新区域,根据背景变化的程度,利用动态权值更新学习率,使用基于单高斯背景模型方法,结合逻辑"或"运算检测出车辆。实验结果表明,该算法能够快速准确地检测出车辆,并且在背景更新过程中实现了自适应,并具有一定的鲁棒性。

| Abstract: | For the problem that it is difficult to take into account real-time,accuracy and adaptability together in vehicle detection,a fast and effective vehicle detection algorithm is proposed.By using threshold values,the background area and the update region are determined,and by using dynamic weights,learning rates are updated in accordance with the degree of changes in background.With logical or operator,vehicles are detected based on a single Gaussian background model.The experimental results show that this ... |
