mosaic_tiles_sites — PRINTPATH `npr` op

• 資料種類:image2d → pairs

• 呼叫: import fullseye as fs; fs.ledger.mosaic_tiles_sites(image, n_tiles=400, iterations=12, seed=0, weighted=True)(要直接呼叫實作,import printpath; printpath.mosaic_tiles_sites(image, n_tiles=400, iterations=12, seed=0, weighted=True);從台帳取用則 opsprintpath.get("mosaic_tiles_sites"))

用法

在影像上執行的 Lloyd 迭代 —— 馬賽克的磁磚中心。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

Places *n_tiles* sites and moves each to the centroid of the pixels it owns,

weighted by local contrast when *weighted* (so detail gets smaller tiles).

★Why this earns its place: Lloyd's iteration is a descent — the

quantisation energy cannot increase — and that is a property of the algorithm,

not of the picture. The energy is *not* reported here on purpose: the existing

`stipple_energy` measures it from the sites, so the monotonicity can be

checked by an op that did not produce them. Measuring your own descent with

your own number proves nothing.

Returns `pairs`: the site coordinates (row, col).

Raises `ValueError`: fewer than 4 tiles or more tiles than pixels;

negative iterations; a non-finite or oversized image.
