tb_integrate_funct_1d — 2D typed op

• 数据种类:signal → signal

• 调用:fullseye.apply(img, "tb_integrate_funct_1d", a=0.5, b=0.5)(2-D 的模型是一张图 + 两个标量旋钮 a,b∈[0,1])

用法

使用梯形法则计算累积积分(HALCON `integrate_funct_1d`)。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

`out[i]` is the integral of *y* from x=0 to x=i in **y-units times

samples** (multiply by the physical sample spacing `dt` yourself);

`out[0]` is always 0. For smooth signals

`integrate_funct_1d(derivate_funct_1d(y)) ~= y - y[0]` to second order.

:param y: 1-D function, at least 1 sample (a single sample integrates to `[0.]`).

:returns: float64 array of the same length.

:raises ValueError: non-1-D / NaN / Inf input, or empty input.

Typed bridge of the 1d op `integrate_funct_1d into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. This op has no tunable parameter; a and b` are unused.
