smooth_funct_1d_gauss — ONED function op

• データ種: signal → signal
• 呼び出し: import fullseye as fs; fs.ledger.smooth_funct_1d_gauss(y, sigma: 'float' = 1.0) (実装を直接呼ぶなら import funct1d; funct1d.smooth_funct_1d_gauss(y, sigma: 'float' = 1.0)、台帳から引くなら ops1d.get("smooth_funct_1d_gauss"))

使い方

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.
