smooth_funct_1d_gauss — ONED function op

• 数据种类:signal → signal

• 调用: import fullseye as fs; fs.ledger.smooth_funct_1d_gauss(y, sigma: 'float' = 1.0)(要直接调用实现,import funct1d; funct1d.smooth_funct_1d_gauss(y, sigma: 'float' = 1.0);从台账取用则 ops1d.get("smooth_funct_1d_gauss"))

用法

> 该算子的说明尚无译文,以下照原文给出。

Gaussian smoothing of a 1-D function (HALCON `smooth_funct_1d_gauss`).

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`.
