Embodiment Construction
[0032] like figure 1 Shown, the present invention realizes as follows:
[0033] (1) Apply the Gaussian mixture model to the first 50 frames of the video for background modeling, effectively remove the interference of small changes in the foreground objects in the background to the extraction of moving targets, and reduce the requirements for the video sequence of target extraction.
[0034] (2) The next frame image in the video is subtracted from the background image obtained by Gaussian mixture model background modeling to obtain the foreground image.
[0035] (3) When the moving object has a large similarity with the background tone, the foreground object in the obtained foreground image is incomplete, so the expansion operation is performed in the foreground image to merge all the background points that are in contact with the tracking target into the region of interest In , expand the boundary outward, fill the hole in the binarized tracking target, and fill the incomplet...
