YouTube-VOS 2018 Benchmark (Semi-Supervised Video Object Segmentation)
The semi-supervised scenario assumes the user inputs a full mask of the object(s) of interest in the first frame of a video sequence. Methods have to produce the segmentation mask for that object(s) in the subsequent frames.

The chart needs JavaScript; the table below carries every value.
Direction inferred from the metric name, not from the archive: Params(M) (lower is better). Not inferred (points only, no best-so-far line): Overall, Jaccard (Seen), Jaccard (Unseen), F-Measure (Seen), F-Measure (Unseen), Speed (FPS), Speed (FPS). Points are placed at the row's paper date; 53 of 53 rows carry one.
Results archive 2025-07-28
Archive rows end at the archive snapshot, 2025-07-28: no result published after that date is in this table. Rank is the archive's row order at that snapshot; not re-ranked here. Metric values are the archive's strings. Column headers sort the table in your browser; each row keeps its archive rank.

Syntology Ran reads "N of M ran · U unverified": of the M code samples Syntology harvested from repositories linked to that row's paper (joined by arXiv id), N executed on a synthesized input and the other U = M−N are unverified (harvested, no recorded run). It counts code from repositories linked to that row's paper, not this result: the row's number was not reproduced and nothing here is a correctness claim. The other cell texts mean no graph line for the row: "linked, not harvested" (the archive links code, Syntology has not harvested it), "no code linked" (no code link in the archive), "not matched" (the row's paper URL matched no paper on this site). 16 rows have a graph line, from 11 distinct papers; 13 rows (8 papers) have at least one sample that ran. Counting each paper once: Syntology ran 31 of 69 samples; 38 unverified. Separately, 13 of those 69 are pointer-only (licence): the site points at that code rather than redistributing it, a licence property recorded for ran and unverified samples alike; each cell's tooltip carries the row's own pointer-only count. Read from the graph 2026-09-24. Per-sample status is on the paper page.
