時間頻帶內逐像素的均方功率 -> `(H, W)` 圖。
> 以下的詳細說明為原文 —— 摘要與標題已翻譯。
"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.
