FSC147 Benchmark (Few-shot Object Counting and Detection)
Few-shot Object Counting and Detection aims to count and detect instances of objects of the same class as given exemplars within a single image, using only up to three exemplars from the original FSC147. This task is especially challenging but crucial when large datasets are unavailable. Methods for this task must output a single set of bounding boxes, from which the final count is derived based on the number of detected boxes.

The chart needs JavaScript; the table below carries every value.
Direction inferred from the metric name, not from the archive: MAE(test) (lower is better), RMSE(test) (lower is better), AP(test) (higher is better). Not inferred (points only, no best-so-far line): AP50(test). Points are placed at the row's paper date; 4 of 4 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). 2 rows have a graph line, from 2 distinct papers; 1 rows (1 papers) have at least one sample that ran. Counting each paper once: Syntology ran 16 of 22 samples; 6 unverified. Separately, 0 of those 22 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.
