keypoints_uv_to_rowcol — REPRCONV `keypoint` op

• Data kinds: keypoints → keypoints

• Call: import fullseye as fs; fs.ledger.keypoints_uv_to_rowcol(keypoints) (to call the implementation directly, import reprconv; reprconv.keypoints_uv_to_rowcol(keypoints); from the registry, opsreprconv.get("keypoints_uv_to_rowcol"))

• GPU: none (CPU reference implementation only)

Usage

Image points (u, v) = (col, row) → (row, col). The reverse of keypoints_rowcol_to_uv.

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

Args:

keypoints: (N, 2) の (u, v)。

Returns:

(N, 2) float64 の (row, col)。

Raises:

ValueError: (N, 2) でない / 非有限 / 空。
