vol_local_maxima — 3D feature op

数据种类:voxelpoints

调用: import fullseye as fs; fs.ledger.vol_local_maxima(vol, min_distance, threshold=None)(要直接调用实现,import volops; volops.vol_local_maxima(vol, min_distance, threshold=None);从台账取用则 ops3d.get("vol_local_maxima"))

用法

3-D 局部极大(峰)检测。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

A voxel is a peak if it equals the maximum over a cubic neighbourhood of

half-width `min_distance (side 2*min_distance + 1`) and that

neighbourhood is not flat (its max strictly exceeds its min, so a constant

region yields no peaks). Pass *threshold* to additionally require

`vol >= threshold` (drop weak peaks in noise).

Returns an `(N, 3) int array of (z, y, x)` peak coordinates. Uses only

`scipy.ndimage.maximum_filter / minimum_filter` (no skimage).
