| 摘 要： | 针对室外视频监控环境复杂,运动对象检测准确性较低,提出一种用于背景减运动对象检测的背景重构算法.综合考虑像素点亮度的稳定状态持续时间和出现频率,定义加权亮度直方图确定量化区间的背景概率,根据背景概率大小和分布,结合基于亮度空间相关性的修正实现背景重构.实验结果表明,重构的背景有效地克服了训练阶段运动对象的干扰,用于运动对象检测能够适应背景扰动、摄像机轻微晃动等复杂情况,提高检测的准确性.

| Abstract: | The accuracy of motion objects detection is low for outdoor complicated visual surveillance,so a background reconstruction algorithm used in background subtraction motion objects detection is proposed.The algorithm integrates the stabilization duration with appearance frequency,and uses weighted intensity histogram to confirm the background probability of quantity interval. Based on the probability values and distributing,it uses the intensity space correlation to amend the background,and realizes the backg... |
