🌟 Summary

Improved NMS time limit scaling with batch size.

📊 Key Changes

• Adjusted the scaling factor for the NMS time limit from 0.03 to 0.05 per batch size (bs).

🎯 Purpose & Impact

• Aimed at better performance scaling with larger batch sizes during Non-Maximum Suppression (NMS).
• Potentially increases processing time allowance for NMS proportionally to batch size, leading to fewer early exits on larger batches.
• Impact may be smoother performance for users with varying batch sizes, but could also result in slightly longer inference times on larger batches. 🕒💡
