tb_sample_funct_1d — 2D `typed` op

• Data kinds: signal → signal

• Call: fullseye.apply(img, "tb_sample_funct_1d", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

*No figure: this op takes signal as input. A Studio program starting from an image cannot reach that type — see the runnable examples below for how it is used.*

Usage

Every *step*-th sample (HALCON `sample_funct_1d`).

Keeps samples `0, step, 2*step, ...` — decimation without an

anti-aliasing filter (smooth first if the signal has content above the new

Nyquist rate).

:param y: 1-D function (may be empty).

:param step: truncated to int, must be >= 1 (`step=1` copies).

:raises ValueError: non-1-D / NaN / Inf input, or `step < 1`.

Typed bridge of the 1d op `sample_funct_1d into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. a drives step (default 2); b` is unused.

References (sample data, literature)

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

Runnable examples (verified samples that actually call this op)
