registration_to_flow2d — MATCHREG intensityreg op

• Data kinds: table → flow2d

• Call: import fullseye as fs; fs.ledger.registration_to_flow2d(result) (to call the implementation directly, import intensityreg; intensityreg.registration_to_flow2d(result); from the registry, opsmatchreg.get("registration_to_flow2d"))

• GPU: none (CPU reference implementation only)

Usage

Extracts the deformation field flow2d ((2,H,W) (dy, dx)) from a registration result table. → flow2d.

向きは deformreg と同じ(動く画像の内容の前向き変位)。piv_flow_magnitude / piv_vorticity / flow_to_rgbimage など flow2d を受ける op へ繋ぐための口。

Args:

result: register_ecc / register_mi / register_ffd の表。

Returns:

(2, H, W) float64 の ndarray(写し)。

Raises:

ValueError: kind="registration" の表でない / 場の形が違う。

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)

• poc_sheet_deformation_ffd — py -3.11 examples/poc_sheet_deformation_ffd.py

Ops the type connects to (they accept flow2d as input)
