tb_quat_normalize_image — 2D typed op

• 資料種類:qimage → qimage

• 呼叫:fullseye.apply(img, "tb_quat_normalize_image", a=0.5, b=0.5)(2-D 的模型是一張圖 + 兩個純量旋鈕 a,b∈[0,1])

*無圖: 該運算子以 qimage 為輸入。從影像開始的 Studio 程式無法到達該型別，請參見下方的可執行範例。*

用法

逐像素歸一化為單位模。→ (H, W, 4)。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

Fail-closed on a zero pixel. A quaternion image routinely contains exact

zeros — a black pixel is `(0,0,0,0)` — so the case is not hypothetical, and

a zero quaternion has no direction to normalise towards. It is refused by

name, with the count and the first offending pixel's row and column in the

message, rather than divided by `norm + eps`: that idiom returns zero, and

a zero used as a rotor becomes the identity rotation with no exception

and no NaN to mark it. (`pose_quat.quat_normalize` did exactly that until

2026-09-01 and now fail-closes too; see :func:quat_color_rotate.)

Raises `ValueError`: any pixel has modulus 0.

Typed bridge of the quat op `quat_normalize_image into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. This op has no tunable parameter; a and b` are unused.
