## Introduction

Referring Video Object Segmentation (R-VOS) methods face challenges in maintaining consistent object segmentation due to temporal context variability and the presence of other visually similar objects. 
We propose **the first end-to-end paradigm that identifies aligned frames for text-conditioned segmentation and propagates mask features to achieve temporally consistent R-VOS..**
Furthermore, we propose **a new Mask Consistency Score (MCS) metric to evaluate the temporal consistency** of video segmentation. Extensive experiments demonstrate that our approach enhances temporal consistency by a significant margin, leading to top-ranked performance on popular R-VOS benchmarks.

## Installation and Data Preparation

Please refer to [SgMg](https://github.com/bo-miao/SgMg) for installation and data preparation.

## Evaluation

The checkpoint for HTR w/ SwinL is available at  [HTR-SwinL](https://drive.google.com/file/d/1dfUuU67NyHV302KfPYMw286nk5VebjG7/view?usp=sharing).

If you want to evaluate HTR on Ref-DAVIS/YouTube-VOS, please run the following command in the `scripts` folder:

```
sh dist_test_davis_swinl.sh
```

```
sh dist_test_ytv_swinl.sh
```

## MCS Metric for Temporal Consistency

The code for MCS evaluation is in `get_mcs.py`. 
Please click `View scoring output log` to download `stdout.txt` of your submission in [Ref-YTVOS eval server](https://codalab.lisn.upsaclay.fr/competitions/3282).

Then you can run the script to get the MCS score under different thresholds.
