hx_move_region — 2D `halcon_ext` op

• Data kinds: region → region

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

• HALCON equivalent: move_region (the HALCON reference is a useful guide to its meaning and parameters)

hx_move_region: 入力 → 出力

*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).*

Usage

Translate a region (dy = a, dx = b, taken as offsets around zero).
