| Count | Number | What it counts |
|---|---|---|
| image placements | 51,303 | every displayed image occurrence in each stored document |
| candidate picture regions | 51,063 | displayed pictures after merging tiles and duplicate draws; each carries a class, possibly still unknown |
| candidate regions still unclassified | 1,801 | candidate regions whose class is still unknown (picture classified unknown, or no picture and no class hint) |
| unique photographs | 40,154 | photographic content: one per distinct pixel stream, with pairs CONFIRMED identical by comparison counted once (suggested pairs are not merged) |
| unique photographs classified by rule only | 40,154 | of which classified by rules alone and not yet confirmed by a model or a person |
| photograph occurrences | 43,771 | every issue, page or gallery context in which those photographs appear (once per page) |
| searchable photographs | 40,154 | unique photographs with a working preview and a search representation |
| look-alikes awaiting a decision | 1,611 | perceptual-hash pairs not yet resolved by comparison (suggested or needing review); none of them is merged |
Rules help classify and never discard. A small historical portrait, or a photograph reproduced in several issues, is kept. Counts that rest on rule-only classification stay marked provisional until a model or a person has confirmed them.
