OVIS (Occluded Video Instance Segmentation)

Introduced by Jiyang Qi et al. in Occluded Video Instance Segmentation: A Benchmark2 Feb 2021 archive 2025-07-28

OVIS is a new large scale benchmark dataset for video instance segmentation task. It is designed with the philosophy of perceiving object occlusions in videos, which could reveal the complexity and the diversity of real-world scenes. OVIS consists of:

  • 296k high-quality instance masks
  • 25 commonly seen semantic categories
  • 901 videos with severe object occlusions
  • 5,223 unique instances

29 shown of 29 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 75. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
