tb_smooth_funct_1d_gauss — 2D typed op

• 資料種類:signal → signal

• 呼叫:fullseye.apply(img, "tb_smooth_funct_1d_gauss", a=0.5, b=0.5)(2-D 的模型是一張圖 + 兩個純量旋鈕 a,b∈[0,1])

用法

對一維函數進行高斯平滑(HALCON `smooth_funct_1d_gauss`)。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

Convolves *y* with a Gaussian of standard deviation *sigma* (in samples),

`reflect` boundary handling (scipy default). The DC level is preserved;

zero-mean noise variance shrinks by roughly `1 / (2 * sigma * sqrt(pi))`.

:param y: 1-D function, at least 1 sample.

:param sigma: Gaussian standard deviation in samples; must be finite and > 0.

:returns: smoothed float64 array, same length as *y*.

:raises ValueError: non-1-D / NaN / Inf input, empty input, or `sigma <= 0`.

Typed bridge of the 1d op `smooth_funct_1d_gauss into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. a drives sigma (default 1); b` is unused.
