### Dataset Summary

**La**rge-scale **S**ingle **O**bject **T**racking (**LaSOT**) aims to provide a dedicated platform for training data-hungry deep trackers as well as assessing long-term tracking performance.

This repositoy contains the new subset provided in the journal version of LaSOT (commonly called **LaSOT<sub>ext</sub>**), published on IJCV ([LaSOT: A High-quality Large-scale Single Object Tracking Benchmark](https://arxiv.org/abs/2009.03465)).

For the training/testing splits of LaSOT (conference version), visit this [repo](https://huggingface.co/datasets/l-lt/LaSOT).

## Download

You can download the whole dataset using Git (with Git LFS):

```bash
git clone https://huggingface.co/datasets/l-lt/LaSOT-ext
```

Alternatively, download the videos of a specific category manually from this [page](https://huggingface.co/datasets/l-lt/LaSOT-ext/tree/main).

LaSOT<sub>ext</sub> can also be downloaded from:

* In one zip file: [OneDrive](https://1drv.ms/u/s!Akt_zO4y_u6DgoQrvo5h48AC15l67A?e=Zo6PWx) or [Homepage server](http://vision.cs.stonybrook.edu/~lasot/data/LaSOT_extension_subset.zip)
