中文说明：应用背景在提取运动车辆的过程中，由于光照强度的变化，造成在提取过程中，将阴影作为运动目标处理，影响检测的准确性。因此，在提取目标之前去除车辆阴影。关键技术首先，提取视频图像的背景图像，再通过分析灰度直方图得到阀值分割的参数，得到去除阴影的二值图。将经过形态学处理和滤波处理的图像采用边缘检测的方法消除阴影。并将两种方法进行关系运算，得到更好的消除效果。
English Description：
Application backgroundIn the process of extracting the moving vehicle, due to the change of illumination intensity, the shadow is processed by the moving object, and the accuracy of the detection is affected.. Therefore, removing the vehicle shadow before extracting the target.Key TechnologyFirstly, extract the background image of the video image, and then through the analysis of gray histogram obtained threshold segmentation parameters, gets rid of the shadow of the binary image. Edge detection method is adopted to remove the shadow from the image edge detection.. And the relationship between the two methods, get better elimination effect.
