运 动 对 象检测在面向对象的视频编码、基于内容的检索、安全监控等领域
都有重要用途,特别是在安全监控应用中,运动对象检测是基于视频的安全监
控异常报警任务的关键算法。由于实际监控背景一般比较复杂,例如背景中的
树枝叶晃动、场景照明亮度的变化等都会对运动对象检测造成影响,因此复杂
场景下的运动对象检测不是一项简单的任务。另外,当摄像机运动时,由于图
像背景是不断变化的,进一步增加了运动对象检测的复杂性。-Detection of moving objects in objec

针对摄像机固定下的复杂背景环境,对采集到的视频图像的图像数据用混合高斯背景建模方法实现前景/背景分割,实现运动目标检测和跟踪。在进行前景检测前,先对背景进行训练,对图像中每个背景采用一个混合高斯模型进行模拟,每个背景的混合高斯的个数可以自适应。然后在测试阶段,对新来的像素进行GMM匹配,如果该像素值能够匹配其中一个高斯,则认为是背景,否则认为是前景。由于整个过程GMM模型在不断更新学习中,所以对动态背景有一定的鲁棒性。最后通过对一个有树枝摇摆的动态背景进行前景检测,取得了较好的效果。-For c
