Embodiment Construction
[0048] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0049] figure 2 It is a flowchart of a queuing anomaly detection method based on logistic regression, which mainly includes the following steps:
[0050]Step 101, extract a frame from the collected monitoring video when there is no customer as the background image, and the monitoring video image when the service is normally provided as the image to be judged, extract the region of interest that needs to detect the window, and specify the window to be detected Extract the region of interest from the background image and the image to be judged separately, and use the region function cvRect(int x, int y, int width, int height) to extract the region of interest image according to the position of the region of interest in the image, where x represents The x coordinate of the upper left corner of the region, y represents the y coordinate of the upper left c...
