Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing.
[0017] combine figure 2 , the concrete implementation steps of the present invention are as follows:
[0018] Step (1). Extract the HOG, CN and color histogram respectively on the estimated position and scale of the target in the previous frame in the current frame Figure three Candidate samples for positions of various features. Based on the multi-channel correlation filtering algorithm, the HOG and CN characteristic response maps are obtained respectively through the position correlation filter. The color histogram characteristic response map is obtained through the color histogram filter and integral map technology.
[0019] 1.1 Multi-channel correlation filter tracking algorithm
[0020] Denote the d-channel target appearance template as f, and the feature representation of each channel as f l ,l∈{1,...,d}. Denote the correlation filter as h, which consists of d...
