基于局部OGHM的视频运动目标检测算法

Moving targets detection using local OGHM

针对原有3D OGHM视频运动检测算法在视频分辨率较高时效率偏低的问题,从参与计算的图像分辨率角度提出了一种改进思想,即:将OGHM计算限制在"潜在目标邻域"等对检测有重要作用的像素范围内进行,阻止其他非重要像素点参与OGHM计算,从而来提高3D OGHM的算法效率。提出了局部OGHM运动检测算法(LOGHM),并深入分析了改进前后两种检测算法的效率特性,给出了确定"潜在目标邻域"的常用准则。试验结果表明,LOGHM不但有较高的计算效率,而且还有很好的抗干扰能力。

The efficiency of the 3D OGHM detection algorithm will be at a very low efficiency level if the resolution of the video is high.Concerning this problem,this paper proposed a new idea in the sense of the resolution of the image that participated in the computation.It is to limit the computation of OGHM in some special regions(for example,the neighbors of the potential targets),which is important for motion detection,while to prevent other unimportant pixels from the computation of detection.Following the ide...
