find_ncc_models — MV detect op

• Data kinds: table × image2d → table

• Call: import fullseye as fs; fs.ledger.find_ncc_models(model, image, min_score=0.5, max_matches=10, min_distance=5) (to call the implementation directly, import shapematch; shapematch.find_ncc_models(model, image, min_score=0.5, max_matches=10, min_distance=5); from the registry, opsmv.get("find_ncc_models"))

• HALCON equivalent: find_ncc_models (the HALCON reference is a useful guide to its meaning and parameters)

• GPU: none (CPU reference implementation only)

Usage

Find one or more NCC models in one image.

> The detailed description below is the original text — the summary and the headings are translated.

model がモデルのリストなら全モデルを探し、各一致に model(リストの添字)を付けてスコアの順に並べ、min_distance より近い一致は強い方だけ残す。一致が無いと matches が空で num が 0 を返す(理由: 見つからないのは正常な結果)。空の入力(model のリストが 0 要素)は ValueError。

model が 1 つのときは min_distance を共通検索核へ渡す旧入口のまま。

References (sample data, literature)

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.

Runnable examples (verified samples that actually call this op)

• machine_vision_tour — py -3.11 examples/machine_vision_tour.py
