基于抑制光线强度变化影响的运动目标检测

在运动目标检测过程中,若两帧图像拍摄条件下光线强度不同,则运动目标检测的结果将会受到影响。据此,该文提出了抑制光线强度变化影响的运动目标检测方法。首先,对两帧图像通过自适应高斯核平滑滤波器处理,以降低图像的随机噪声对处理结果的影响;然后,根据两帧图像对应像素的灰度变化量信息,判断该两帧图像的光强变化程度;最后,根据本文所研究的抑制光线强度变化影响的方法,将运动目标从背景中检测出来。实验证明,取得了良好的效果。

Detection of Moving Objects by a Restraining the Influence of Changing Beam

In the course of the detection of moving objects, the results of detection will be affected by two different beam conditions in shooting. Therefore, a new method for detecting moving objects by restraining the influence of changing beam is proposed in this paper. Firstly, the two different frames are manipulated using Guassian kernel adaptive smooth filter, in order to suppress the random noise on the images. Secondly, the degrees of the changes about beams of the different frames are judged according to the information of the changes between two frames. Finally, the moving objects from the backgrounds are detected by using the method presented in this paper.
