| 摘 要： | 针对多目标检测中目标和阴影连接导致检测失败的问题,提出一种基于改进水平集的精确检测方法.通过对监控视频进行对称差分获取运动信息,将其融合到水平集演化函数中,然后进行一次分割得到演化曲线,以此获得目标的位置信息.根据目标与阴影的差异信息,调整水平集演化函数,进行二次分割可准确分离多个目标及其阴影.将文中方法应用在公路监控的多运动车辆检测实验中,能够有效地检测出运动车辆轮廓,处理速度为24帧/s,消除阴影的准确率达98.6%,取得了准确的检测效果.

| Abstract: | In the case of multiple moving object detection,the join of objects and shadow always leads to the failure of object detection.To solve this problem,an improved level set method is proposed.Moving information is extracted via symmetrical difference and it is merged into the velocity function of level set.The evolved curve is obtained after the first segmentation,hence the information of object location could be found.According to the information difference between object and shadow,the velocity function of ... |
