Vision Based Dynamic Offside Line Marker for Soccer Games

[AtomScott]

1. Overview (basic ideas)

Baseline method for offside detection in football games.

2. Novelty

• No knowledge of the camera orientations nor any pre-trained models is assumed
• Real-time inference.
• FIFA 18 game-play videos as training data

3. Method (Technical details)

• Hough transform
• Connected components
• KLT tracking
• Color similarity
  

4. Results

FP = False Positives, FN= False Negatives, SC = Stadium Configuration, BCC = Boundary Line Connected Components.

6. Thoughts, Comments

• Lacks validation
• Should test on real-world data, they don't so its probably not that robust
• Probably be able to reimplement in a week from scratch if given the data.
