[0046] A novel video tracking method based on adaptive block, wherein the video includes M frames of images, m=1, marking the target area to be tracked in the mth frame of images, and the specific steps include:
[0047] (1) Divide the target area into N initial blocks of the same size, N=10;
[0048] (2) Perform steps A-E for each initial block i obtained in step (1), where 1≤i≤N:
[0049] A. Calculate the variance D of the pixel value of the pixel point of the initial block i currenti ;
[0050] B. Pre-divide the initial block i into p sub-blocks of the same size, and calculate the variance D of the pixel values of the pixels of each sub-block subij,即 :{D subi1 ,D subi2 …D subip}, p=4;
[0051] C, the variance D of the pixel values of the pixel points of the p sub-blocks described in step B subij The variance D of the pixel value of the pixel point of the initial block i after addition currenti For comparison, if the variance D of the pixel values of the pixe...
