The 8th LSVOS challenge will be held in conjunction with ECCV 2026 in Malmö, Sweden. This year, we will continue the same setup as last year and still have two tracks: VOS and RVOS. In the Video Object Segmentation (VOS) track, we will utilize LVOS and MOSE. to study the VOS under more challenging complex environments. LVOS is designed for long-term videos, dealing with complex object motion and long-term reappearance, while MOSE focuses on complex scenes, covering aspects such as object disappearance and reappearance, inconspicuous small objects, heavy occlusions, and crowded environments. For the Referring Video Object Segmentation (RVOS) track, we will continue to use MeViS. MeViS focuses on the identification of the target object in a video based on motion-related descriptions rather than static attributes. This innovative approach subverts the foundational design principles of existing RVOS methods, compelling researchers to engage in a more in - depth exploration and reevaluation of motion modeling. In addition, we will hold a series of talks by the leading experts in video understating and embodied intelligence. In this year, the following topics will be covered:

• Semantic/panoptic segmentation for images/videos
• Video Object Segmentation in Complex Scenes
• Long-term Video Object Segmentation
• Referring Video Object Segmentation
• Video Segmentation with Motion Expressions
• Vision and Language
• Cognitive Models of Object Perception
• Real-world Understanding and embodied intelligence

[Update] LSVOS 2026 paper submission details will be announced soon. Stay tuned!

We invite authors to submit unpublished papers (8-page ECCV format) to our workshop, to be presented at a poster session upon acceptance. All submissions will go through a double-blind review process. Submission portal link will be announced later.

Accepted papers will be published in the official ECCV Workshops proceedings and the Computer Vision Foundation (CVF) Open Access archive.

The 8th LSVOS challenge includes three tracks: Complex VOS (MOSEv2), Classic VOS and RVOS.

Below are the links and task descriptions for the three tracks:
