## 🔥 Latest News

- **[2024-10-27]** To provide a benchmark for the task of language reference, such as 'Tracking by natural language specification' and 'Referring video object segmentation', we added the language description of the object in meta json.
- **[2024-10-24]** [SAM 2++ model](https://github.com/MCG-NJU/SAM2-Plus) and part of [Tracking-Any-Granularity dataset](https://huggingface.co/datasets/MCG-NJU/tracking-any-granularity) are released. Check out the [project page](https://tracking-any-granularity.github.io/) for more details.

## Dataset Summary

**T**racking-**A**ny-**G**ranularity (TAG) is a comprehensive dataset for training our unified model, termed Tracking-Any-Granularity (TAG), with annotations across three granularities: segmentation masks, bounding boxes, and key points.

## Dataset Description

Our dataset includes **a wide range of video sources**, demonstrating strong diversity and serving as a solid benchmark for evaluating tracking performance. Each video sequence is annotated with **18 attributes representing different tracking challenges**, which can appear simultaneously in the same video. Common challenges include motion blur, deformation, and partial occlusion, reflecting the dataset’s high difficulty. Most videos contain multiple attributes, indicating the dataset’s coverage of complex and diverse tracking scenarios.
