🌟 Summary

Enhanced bbox_iou function for better intersection-over-union (IoU) calculations. 📐

📊 Key Changes

• Adjusted width (w) and height (h) calculations by adding an epsilon (eps) to avoid division by zero.
• Simplified the consistency term v in the Complete IoU (CIoU) calculation by removing unnecessary epsilons.

🎯 Purpose & Impact

• 🛠️ Prevention of potential division by zero errors when calculating bounding box dimensions, improving robustness.
• 📈 Increased numerical stability and precision of IoU-related metrics, which could lead to more reliable model evaluations and training.
• 🧠 These updates help ensure the object detection is as accurate as possible, which is essential for applications relying on precise object localization.
