🎉 Basketball Analysis System - WORKING! ✅

Test Results: SUCCESS!

Your basketball analysis system is now fully functional and has successfully analyzed a test video!

✅ Test Completed Successfully

Input

  • Video: input_videos/video_1.mp4 (4.24 MB)
  • Duration: 20 frames
  • Processing Time: ~7 minutes (CPU only)

Output

  • File: output_videos/test_output.avi (8.1 MB)
  • Status: ✅ Created successfully
  • Analysis: Complete with all features

🔧 Issue Fixed

Problem: Import error for BallAquisitionDetector

  • The class was in ball_aquisition_detector.py at root level
  • Import expected it in ball_aquisition/ module

Solution:

  • Moved file to proper module directory
  • Created ball_aquisition/__init__.py to export the class
  • ✅ Import now works correctly

📊 What Was Analyzed

The system successfully performed:

  1. ✅ Player Detection & Tracking - Detected 7-11 players per frame
  2. ✅ Ball Detection & Tracking - Detected basketball with interpolation
  3. ✅ Court Keypoint Detection - Identified court lines and zones
  4. ✅ Team Assignment - Used CLIP model for jersey color classification
  5. ✅ Ball Possession - Determined player possession
  6. ✅ Pass Detection - Identified passes between players
  7. ✅ Interception Detection - Detected intercepted passes
  8. ✅ Tactical View - Created top-down mini-map
  9. ✅ Speed & Distance - Calculated player movement metrics

Detection Results (Sample Frames)

  • Frame 0: 8 Players, 2 Balls, 1 Hoop, 3 Refs, 1 Scoreboard
  • Frame 5: 9 Players, 1 Ball, 1 Hoop, 1 Ref
  • Frame 10: 10 Players, 2 Balls, 1 Hoop
  • Frame 15: 7 Players, 1 Hoop
  • Frame 19: 11 Players, 1 Hoop

🚀 How to Run Analysis

Option 1: Using the Convenience Script 

cd /home/okidi6/Documents/Personalised-AI-Basketball-Skill-Analysis-System./back-end
./run.sh input_videos/video_1.mp4

Option 2: Using Python Directly 

cd /home/okidi6/Documents/Personalised-AI-Basketball-Skill-Analysis-System./back-end
source venv/bin/activate
python main.py input_videos/video_1.mp4 --output_video output_videos/my_output.avi

Option 3: Using Test Script 

cd /home/okidi6/Documents/Personalised-AI-Basketball-Skill-Analysis-System./back-end
source venv/bin/activate
python test_system.py --video input_videos/video_1.mp4

📁 Output Location

Analyzed videos are saved to:

/home/okidi6/Documents/Personalised-AI-Basketball-Skill-Analysis-System./back-end/output_videos/

Current output:

  • test_output.avi (8.1 MB) - ✅ Successfully created!

⚡ Performance Notes

Processing Speed (CPU Only)

  • ~1 second per frame (979.7ms inference time)
  • 20 frames processed in ~7 minutes total
  • Includes: detection, tracking, team assignment, analysis, and rendering

Stub Caching

The system created cached files in stubs/:

  • player_track_stubs.pkl (56 KB) - Player detections
  • ball_track_stubs.pkl (2.8 KB) - Ball detections
  • court_key_points_stub.pkl (63 KB) - Court keypoints

Benefit: Next run on same video will be much faster!

🎥 View Your Results

To view the analyzed video:

# Using default video player
xdg-open output_videos/test_output.avi

# Or using VLC
vlc output_videos/test_output.avi

# Or using mpv
mpv output_videos/test_output.avi

The video includes:

  • Player bounding boxes (color-coded by team)
  • Ball tracking visualization
  • Court keypoint overlays
  • Team ball control statistics
  • Pass and interception markers
  • Tactical view (mini-map)
  • Player speed and distance metrics
  • Frame numbers

🎯 Next Steps

1. Test with More Videos 

# Test with other sample videos
python main.py input_videos/video_2.mp4
python main.py input_videos/video_3.mp4
python main.py input_videos/video_4.mp4

2. Add Your Own Videos

  • Place basketball videos in input_videos/
  • Recommended: 10-30 second clips for testing
  • Supported formats: MP4, AVI

3. Optimize Performance

  • Consider installing CUDA-enabled PyTorch for GPU acceleration
  • Current: ~1 second per frame (CPU)
  • With GPU: Could be 5-10x faster

4. Integration

Once satisfied with results:

  • Integrate with FastAPI backend
  • Add video upload endpoints
  • Implement async processing
  • Store results in Supabase
  • Connect to frontend
