give_bg_esti — MV tracking op

• Data kinds: table → image2d

• Call: import fullseye as fs; fs.ledger.give_bg_esti(model) (to call the implementation directly, import mvtrack; mvtrack.give_bg_esti(model); from the registry, opsmv.get("give_bg_esti"))

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

• GPU: none (CPU reference implementation only)

Usage

Return a copy of the model's current background image.

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

空の入力は無い(モデルは create_bg_esti が必ず 1 画素以上で作る)。形の違う値は ValueError。

Args:

model: create_bg_esti の返り。

Returns:

背景の float 画像。

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
