Coral Cover: Maluku 2018

Shaded value = in the CV mean (shade deepens with cover) Grey italic = shown for comparison but left out of the CV mean: the gold standard and manual CoralNet annotations (human reference values, not models), Coralscapes (not trusted), and any value that reuses the reference's own data n = frames behind the value — = not run or not applicable (see each region's notes) Site names and method names link out (new tab)

Notes for Maluku 2018 - Banda (11)

[a] No gold standard exists (no transect, no frames manually annotated in CoralNet).
[b] Not applicable: no CoralNet source / hand annotations exist for these photos.
[c] Value read from cv_method_tables.json (injector output, generated 2026-09-28 22:33); the scope text there gives denominator and frame set.
[d] DINOv3 (in-house, frozen Alor/Indonesia model) = mean hard-coral probability over 20 synthesized points per photo, NO water/fish class, so not a benthic denominator (from the map build's hard_coral_cover_by_site.csv).
[e] Coralscapes (v1 EPFL-ECEO/coralscapes-vit-b-dpt; v2 coralscapesv2-dinov3-vitb-lora-dpt) is not trusted (Anderson): shown, never averaged. Area fraction, not a point count.
[f] Not run: EDITED region by ruling; unedited originals exist but were never staged for CoralSCOP.
[g] CoralSCOP = per-frame sum of colony-mask area fractions (zero-filled; overlapping masks double-count), averaged over frames with an ok row. Area index, not a point count: denominator differs from any point-count reference.
[h] Claude = blind 7-call point count on the EDITED photos, 20 points per photo, (HC+BL)/(20 − WATER − FISH − OBST), UNK kept in; mean across photos (arm ledgers, via cv_method_tables.json).
Mean/Range: Mean ± SD and Range are over the CV cells that enter the mean (CoralNet where independent, DINOv3, CoralSCOP unedited/edited, Claude). Gold standard, frames manually annotated in CoralNet, Coralscapes and same-measurement cells are shown but never averaged (*).
Methods: Claude (Anthropic); DINOv3 (Meta; paper; used here as the frozen backbone of the in-house classifier); Coralscapes v1 and v2 (EPFL-ECEO; dataset paper, code); CoralSCOP (Zheng et al., CVPR 2024); CoralNet.
Sites: names drop the region prefix (hover for the full name) and link to the site's CRD page, or to the regional summary page where the site has none. Date = survey date from the map pins (first–last visit); sites are listed earliest first, undated sites last.
