+# MMOT: The First Challenging Benchmark for Drone-based Multispectral Multi-Object Tracking
+
+The MMOT dataset was presented in the paper [MMOT: The First Challenging Benchmark for Drone-based Multispectral Multi-Object Tracking](https://huggingface.co/papers/2510.12565).
+
+The official code and further details can be found on the GitHub repository: [https://github.com/Annzstbl/MMOT](https://github.com/Annzstbl/MMOT).
+
+## Introduction
+
+**MMOT** is the *first* large-scale benchmark for **drone-based multispectral multi-object tracking (MOT)**. It integrates **spectral and temporal cues** to evaluate modern tracking algorithms under real-world UAV conditions. Drone-based multi-object tracking is essential yet highly challenging due to small targets, severe occlusions, and cluttered backgrounds. This dataset aims to bridge the gap by providing crucial multispectral cues to enhance object discriminability under degraded spatial conditions.
+
+## ✨ Highlights
+
+-   **📦 Large Scale** — 125 video sequences, 13.8K frames, 488.8K annotated oriented boxes across 8 categories
+-   **🌈 Multispectral Imagery** — 8-band MSI covering visible to near-infrared spectrum
+-   **📐 Oriented Bounding Boxes (OBB)** — precise orientation labels for robust aerial association
+-   **🚁 Real UAV Scenarios** — varying altitudes (80–200 m), illumination, and dense urban traffic
+-   **🧩 Complete Codebase** — integrates 8 representative trackers (SORT, ByteTrack, OC-SORT, BoT-SORT, MOTR, MOTRv2, MeMOTR, MOTIP)

+
+## 📂 Dataset Download and Preparation
+
+The **MMOT dataset** can be obtained from this Hugging Face repository. On Hugging Face, each video sequence is **individually packaged** into a `.tar` file to support **Croissant file generation**.
+
+Each `.tar` archive contains:
+- Multispectral frames in `.npy` format
+- Frame-wise MOT annotations in `.txt` format (one annotation per frame)
+
+Example (root folder):
+
+```text
+MMOT_DATASET
+├── train
+│   ├── data30-8
+│   │   ├── 000001.npy
+│   │   ├── 000001.txt
+│   │   ├── 000002.npy
+│   │   ├── 000002.txt
+│   │   └── ...
+│   └── ...
+├── test
+```
+Please download all .tar files and place them into the corresponding `train/` or `test/` folder.
+Then, you can automatically extract and convert the structure to the MMOT standard format using:
+
+```bash
+python dataset/huggingface_tar_to_standard.py --root /path/to/root
+```
+This script will reorganize all tar files and transform the Hugging Face structure into the standard MMOT format.
+
+📁 **Standard Directory Layout**
+
+After processing (from either source), your dataset directory should appear as follows:
+```text
+MMOT_DATASET
+├── train
+│   ├── npy
+│   │   ├── data23-2
+│   │   │   ├── 000001.npy
+│   │   │   └── 000002.npy
+│   │   ├── data23-3
+│   │   └── ...
+│   └── mot
+│       ├── data23-2.txt
+│       ├── data23-3.txt
+│       └── ...  
+└── test
+    ├── npy
+    └── mot
+```
+
+Once the dataset has been organized in the above structure,  
+please link it to the main project directory for unified access:
+
+```bash
+# Link dataset to project root
+ln -s /path/to/MMOT_dataset ./data
+```
