temporal_band_power — MOTIONMAG temporal op

使い方

Per-pixel mean-square power inside a temporal band -> (H, W) map.

“Where in the frame is something moving at this frequency?” — a resonance map. The value at a pixel is the mean over time of the squared band-passed signal, so a pure sinusoid of amplitude a inside the band reads exactly a^2/2 (Parseval; measured relative error 3.08e-16 for a = 0.3).

This is an analysis map, not a displayable image: it is a power and is not bounded by 1. Pixels with no in-band content read 0.
