tb_get_y_value_funct_1d — 2D `typed` op

• Data kinds: signal → feature

• Call: fullseye.apply(img, "tb_get_y_value_funct_1d", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

Usage

The y-value at (fractional) position *x* (HALCON `get_y_value_funct_1d`).

With `interpolate=True` (default) the value is linearly interpolated

between the two neighbouring samples; with `interpolate=False` the nearest

sample is returned.

Domain policy (documented, not extrapolated): *x* outside `[0, n-1]`

clamps to the boundary value (`numpy.interp` end-hold semantics /

index clip). HALCON's `'zero'`-border variant is not offered.

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

:param x: finite scalar position in index units.

:param interpolate: linear interpolation (True) or nearest sample (False).

:returns: float.

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

Typed bridge of the 1d op `get_y_value_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.

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

Runnable examples (verified samples that actually call this op)
