Embodiment

[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...

Abstract

The invention relates to a novel video tracking method based on self-adaptive partitioning, fully considers difference of pixel values inside a target area, and the video tracking method based on particle filtering realizes efficient and self-adaptive video tracking and improves accuracy and adaptivity of video tracking. For the problems of shielding, interference and the like which occur in video tracking, the video tracking method provided by the invention can maintain a relatively accurate recognition rate, fully considers content information in a video and image, and adaptively adjusts a corresponding partitioning strategy according to characteristics of a tracked target area, thereby achieving a high-intelligence and high-accuracy video tracking effect.
