Basketball Shot Angle Detector

Click "Upload Video" to select a basketball shot video, OR click "Use Camera" for live analysis.

2. The video/camera feed will appear below. Click the Play/Pause button to control playback.

3. As the video plays, The app will attempt to detect a single player's right shoulder, elbow and wrist in real-time. If it does, it will drawing lines connecting the shoulder, elbow and wrist and display the **Elbow Angle** (between upper arm and forearm). It will then determine if a boxed area slightly above their wrist is a basketball. If a basketball is detected, it will then wait a few frames before it's no longer detected and pause the video when this occurs. It will determine this to be the **Release Angle** (between upper arm and a horizontal line from the shoulder). Note for this to work properly, there should only be one person in the frame with a minimal number of other objects and a clear picture of a basketball, preferably taken from the side. The person also needs to be releasing the ball with their right hand.

4. When the video pauses, you can click "Log Current Angle" to record that specific release angle and timestamp if it's indeed a person shooting to maintain a list of release angles.

Note: A possible future feature would be to generate a new video file with overlaid annotations. For now, the annotations are shown live on the video and you could take screenshots if you're using your phone.
