v8.3.114 - `ultralytics 8.3.114` New tracker re-identification (ReID) of lost tracks (#20192)

on Python PyPI

🌟 Summary

This release introduces advanced tracker re-identification (ReID) for object tracking, along with several improvements to documentation, dataset handling, and model export reliability. 🚀🔍

📊 Key Changes

• Tracker Re-Identification (ReID) Support:
  • Added native feature-based and model-based ReID to the BoTSORT tracker, enabling recovery of lost object tracks.
  • Default ReID mode is now auto, using YOLO model features when available.
  • Enhanced feature extraction and association logic for more robust multi-object tracking.
• Documentation Enhancements:
  • Cleaned up code block line numbers and improved guide titles for easier navigation and readability.
  • Added clear instructions for preparing multispectral TIFF images and updated dataset size info for DOTA8 Multispectral.
• Model Export & Metadata Fixes:
  • Ensured the "channels" field is always treated as an integer during MNN export, improving compatibility.
  • Fixed logging for INT8 export calibration to display the correct data path.

🎯 Purpose & Impact

• Smarter Object Tracking:
  • The new ReID feature allows the tracker to re-identify and reconnect lost objects, making tracking more reliable in challenging scenarios (e.g., occlusions or crowded scenes).
  • Users can benefit from improved tracking accuracy with minimal configuration—especially when using YOLO models.
• Better Documentation Experience:
  • Easier-to-read docs and clearer dataset instructions help both new and advanced users get started and troubleshoot more efficiently.
• Smoother Model Deployment:
  • Improved metadata handling and clearer export logs reduce errors and confusion when exporting and deploying models, especially in diverse environments.

Overall, this update brings smarter tracking, a smoother user experience, and more robust model handling to Ultralytics users! 🦾📈
