smoothing op• Data kinds: image → image
• Call: fullseye.apply(img, "simulate_motion", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
• HALCON equivalent: simulate_motion (the HALCON reference is a useful guide to its meaning and parameters)
*The figure is the real output on a synthetic 128×128 input. Left: input, right: output (a non-image return value is shown as the value itself).*
Simulates linear motion blur. Creates a line-segment kernel of length `5+10*b pixels in the direction of angle pi*a (0-180 degrees) and convolves it. Equivalent to HALCON's simulate_motion` (Simulation of (linearly) motion blur.).

`a がぶれの方向角を、b` がぶれの長さを振る。両方が使われる。

• 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.
• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
The program below has been verified to run (same input as the figure). In Studio's help this block becomes buttons that load and run it on the spot.
