动态背景下具有伪装色的运动目标检测

摘要

动态背景下的移动目标检测是视频监控的研究热点之一,具有伪装色的移动目标检测是其中的一个难点.通过分析动态背景下具有伪装色移动目标的颜色变化规律,提出用Laws能量检测和变化频次检测的方法,对动态背景下伪装色目标进行检测.实验表明,这两种方法能够有效地检测某些动态背景下一些具有伪装色的移动目标,即在摄像头固定情况下,对于平缓变化的动态背景中颜色变化幅度较大或者表面纹理复杂的具有伪装色的移动目标,具有良好的检测效果.%The detection of moving objects in the dynamic background is a research focus in video surveillance.Detecting camouflaged moving objects is a challenge.By analyzing the color change of eamouflaged moving objects in dymanic background, we puts forward two methods for defecting camouflaged moving objects using energy of Laws and varying frequency.The experiment shows that,when the camera is fixed, these two methods are effective for detecting camouflaged moving objects in dymanic background when the color of moving objects changes greatly or the moving objects have complicated texture.
