1. A method for detecting a ball shot attempt captured by a single stationary camera, comprising:

  • receiving an input video captured using the single stationary camera, wherein frames of the input video comprise a goal;

    detecting the goal, using a Convolutional Neural Network (CNN) module, by detecting more than one key feature points of the goal from the input video, wherein the CNN module has been trained using one or more prior input videos;

    identifying a ball tracking Region of Interest (ROI) surrounding the goal;

    detecting a ball within the ball tracking ROI over the frames of the input video;

    determining a trajectory of the ball over the frames of the input video; and

    detecting a ball shot attempt by analyzing the trajectory of the ball relative to the goal.
