A few other existing applications of it include: Virtual Offside Line- Grid/Cross-Hair/Triangulation. Split the dataset into train and validation: Build a baseline model for identifying the patch containing ball: Evaluate the model on the validation data: Repeat the similar steps for each frame in a video followed by classification: Have a glance at the frames containing the ball along with the location: Next, we will draw the bounding box around the frames that contain the ball and save it back to the folder: Lets convert back the frames into a video now: How cool is that? New large language models will transform many jobs. A ball tracking system is used to find the path of the ball in a sports video.
