Embodiment Construction
[0065] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0066] Such as figure 1 Shown, the concrete realization steps of the present invention are as follows:
[0067] (1) Build a saliency detector
[0068] After initializing the first frame of image, determine the location of the target and the size of the area, and superimpose appropriate Gaussian noise and rotation transformation on the image block where the target is located, generate a series of positive sample sets of the target, and then randomly collect several such samples in the area outside the target. Large background image patches, as a set of negative samples. When the following image frames are input, the salient regions in the image are first detected by a saliency detector.
[0069] The principle of the saliency detector is to calculate the Euclidean distance between each pixel and the average brightness value of all pixels in the entir...
