Example Embodiment
[0044] Embodiment 1: The present invention provides a method for optimal selection of wireless sensor nodes for visual tracking, which is operated as follows: figure 1 The flow chart of the invention shown.
[0045] (1) For a certain video sensor node i at time t, check whether there is a trigger condition that meets the node selection; here, suppose that the video sensor node i meets a trigger condition at time t;
[0046] (2) Reconstruct the image frame of a certain video sensor node i, and use adaptive Gaussian mixture background modeling for the reconstructed image frame; block the image frame of a certain video sensor node i according to the set size, Calculate the average value of the pixel colors in each image block. Replacing the image block with one pixel having the average value obtains a reconstructed image frame. It is worth noting that the size of image block processing cannot be too large, otherwise the regional differences in the original image will be eliminated o...
