Embodiment 1
[0086] This embodiment provides a long-term video tracking method based on adaptive correlation filtering, see figure 1 , the method includes:
[0087] Step 1. Obtain the first frame of the target, manually determine the center position of the target and the length and width of the bounding box (lx 1 ,ly 1 ,w 1 , g1 ), where lx 1 is the abscissa of the center position of the target, ly 1 is the ordinate of the center position of the target, w 1 is the bounding box width, g 1 is the bounding box height;
[0088] Step 2. According to the center position of the object in the first frame, dense sampling is performed with a step size of 1 pixel; when the overlap ratio of the sample and the object bounding box is greater than 0.9, the sample is assigned a positive label, and when it is less than 0.5, the sample is assigned a negative label. Generate a sample set to train the support vector machine;
[0089] What needs to be explained is that in order to automatically obtain ...
