PASCAL Context-59 Benchmark (Open Vocabulary Semantic Segmentation)
Open-vocabulary semantic segmentation models aim to accurately assign a semantic label to each pixel in an image from a set of arbitrary open-vocabulary texts.

The chart needs JavaScript; the table below carries every value.
Not inferred: mIoU. Points are placed at the row's paper date; 24 of 24 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). 13 rows have a graph line, from 12 distinct papers; 13 rows (12 papers) have at least one sample that ran. Counting each paper once: Syntology ran 37 of 78 samples; 41 unverified. Separately, 22 of those 78 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 2026-09-25. Per-sample status is on the paper page.
Since the archive: results placed by Syntology Syntology
Results that newer papers report for their own method, placed here by Syntology. A model pointed at the cell in the paper's own table; the number was read from that cell and checked against this leaderboard's metric, dataset, split and scale; an independent check that saw this leaderboard's other rows and every other leaderboard on the same dataset accepted it. Not reviewed by the paper's authors or by the archive's editors, and not ranked against the rows above. Measured before publishing: the extractor was run on 883 held-out archive papers and processed 881 of them (the other 2 failed with an error before producing any output and are not part of this measurement); on those 881 papers, a blind reviewer judged 108 of 110 accepted entries correct (95% lower confidence bound 0.9361). Syntology has checked 6,885 of the 9,623 papers on this site that are newer than the archive; results from the others appear after they are checked.

Syntology 1 entry, one per paper, newest first by month (the arXiv date, else the month in the arXiv id), then by arXiv id. Each value is the cell text as the paper prints it; hover "Where in the paper" for the table's caption and each value's column header. Not part of the archive and not in the chart above. Drawn from 6,885 of 9,623 newer papers checked so far.
