Embodiment
[0049] figure 1 It is a flow chart of the target tracking method for fusing multi-scale superpixels of the present invention.
[0050] In this example, if figure 1 As shown, the target tracking method for fusing multi-scale superpixels of the present invention includes the following steps:
[0051] 1) Construct a discriminative appearance model based on superpixels:
[0052] 1.1), obtain superpixel blocks; in a given target tracking sample sequence I 1 , I 2 , I 3 ,…I M Among them, M is the frame number of the sample sequence, for the first frame image I 1 , with (x 1 ,y 1 ) as the center, extract a rectangular area S containing the target with a height of h and a width of w 1 , where h and w are related to the target size h 1 、w 1 The proportional relationship is: h=1.5*h 1 ,w=1.5*w 1 , through the SLIC algorithm for the area S 1 Perform superpixel segmentation of d scales, where d is the total number of layers of the scale, and each layer has N j superpixel bl...
