LGD Cards — Day-2 PoC Video (YOLO card-pip dataset)

Auto-labeled playing-card corner-pip detection tiles from the second day of our proof-of-concept table recordings (Czech Croupier Academy 4K footage), for Live Game Defender (LGD). This is the day-2 training set behind the current served detector lgd-cards-gen3 (holdout recall 0.85).

Format: YOLO — images/{train,val} + labels/{train,val}, data.yaml (52 classes, rank+suit).
~21,084 tiles, serve-matching tiling.
Provenance: boxes.jsonl / manifest.json (per-box origin) + human_corrections.jsonl — this set went through a human-QA pass (14 verified label fixes, incl. a few holdout GT corrections). Labels proposed by a detector, verified/named by an LLM (labeling cost ≈ $8.13). Internal QA review galleries are intentionally not included.

Classes (52)

Standard rank+suit codes (10H, KS, JC, …) — see data.yaml. The detector boxes pips (~2 per card), not whole cards.

⚠️ Honesty note

Our own PoC / academy recordings, not live casino footage; labels are LLM-verified with a partial human pass, not casino-grade ground truth (rule of the project: no real-world casino accuracy claims). Combined with the Public-Domain Roboflow ow27d v4 base (not redistributed here).
