radial_periodogram — DRIVE `terrain` op

• Data kinds: image2d → table

• Call: import fullseye as fs; fs.ledger.radial_periodogram(field, dx: 'float', n_bins: 'int' = 48) -> 'dict' (to call the implementation directly, import driveterrain; driveterrain.radial_periodogram(field, dx: 'float', n_bins: 'int' = 48) -> 'dict'; from the registry, opsdrive.get("radial_periodogram"))

Usage

Radially averages the periodogram of a height field (H, W) on a grid: {"f", "power", "count"} (f in cycles/m).

平均であって環の積分ではない(積分すると f を 1 つ掛けた傾きになる)。DC は除く。
