Abstract: In order to overcome the problems existing in the existing methods, such as high rate of false recognition, high rate of missing recognition and low rate of recognition, an automatic recognition method of basketball shooting action based on background subtraction method is proposed. The background information of the target image is obtained by the background subtraction method to improve the clarity of the whole contour of the moving object. A certain number of video frames are extracted, and the background in the image is effectively separated. The two-dimensional Fourier transform is used to balance the video frames to obtain the foreground target information and the background of the video sequence, so as to complete the automatic recognition of basketball shooting action. Experimental results show that the proposed method can effectively reduce the rate of false recognition and missed recognition, and improve the recognition rate.

Keywords: background subtraction method; basketball shooting; action automatic recognition; optical flow method; error rate.
