vx_nonmax_suppression — VX `suppress` op

• Data kinds: image2d → image2d

• Call: import fullseye as fs; fs.ledger.vx_nonmax_suppression(image, *, window, mask=None) (to call the implementation directly, import vxcore; vxcore.vx_nonmax_suppression(image, *, window, mask=None); from the registry, opsvx.get("vx_nonmax_suppression"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

非極大の抑制(3.39 節)。画素 (x, y) は、窓の中で自分より前(上の行と、同じ行の左)の隣には ≥、後ろの隣には > の

ときだけ残る(REQ-0337)。平らな頂上が 1 画素だけ残るのはこの非対称のため。*mask* の非ゼロ画素は比べず、そのまま残す

(他の画素の比較にも使わない、REQ-0336)。抑制した画素は U8 なら 0、S16 なら INT16_MIN(REQ-0335)。窓の外にはみ出す隣は比べない。

*window*(必須): 奇数の窓の一辺(3, 5, …)。

Raises `ValueError`: U8/S16 の 2-D でない / window が 3 以上の奇数でない / mask の形が違う。

• 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.
