The annotation files have the same formation as Youtube-VIS 2019.

Annotation Tool

We used this platform for the annotation of LV-VIS. This platform is a smart video segmentation annotation tool based on Lableme, SAM, and STCN. See segment-anything-annotator.

Baseline

We provide our baseline OV2Seg code for LV-VIS. Please check Baseline.md for more details.

TODO

• [x] Training and inference code of OV2Seg
• [x] Leaderboard for Val/test set

NOTE:

• We haven't decided to release the annotation file for the test set yet. Please be patient.
• The training set is not exhaustively annotated.
• If you find mistakes in the annotations, please contact us (h.wang3@uva.nl). We will update the annotations.
