quat_norm — QUAT convert op

使い方

Per-pixel quaternion modulus |q| = sqrt(w^2+x^2+y^2+z^2). → (H, W).

Raw / unnormalised, following complexops.cx_magnitude: a modulus is a metric quantity and routinely exceeds one (a QFT spectrum’s DC term is huge). For a colour quaternion it is the colour magnitude — the length of the RGB vector, i.e. luminance in the L2 sense; for a monogenic signal it is the local amplitude and :func:monogenic_amplitude is the name that says so. Use imgio.normalize for a displayable view.
