Show HN: Automatic Baseball Pitching Motion and Trajectory Overlay in Realtime

This project takes your baseball pitching clips and automatically generates the overlay. A fine-tuned Yolov4 model is used to get the location of the ball. Then, I implemented SORT tracking algorithm to keep track of each individual ball. Lastly, I will apply some image registration techniques to deal with slight camera shift on each clip.

I'm still trying to improve it! Feel free to follow this project, also check out the Todo list.

BTW, I just want to point out that did anyone notice that the pitcher throw the ball with the exact same posture but it turned out to fly on a completely different path. It's just amazing!
