typed op• 資料種類:lightfield → image
• 呼叫:fullseye.apply(img, "tb_lf_subaperture", 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])
一個子孔徑視角——透過光瞳上一個點所看到的影像。
> 以下的詳細說明為原文 —— 摘要與標題已翻譯。
Returns a copy of `L[v, u] as a plain (H, W)` 2-D image, so every
other fullseye image operator applies to it unchanged. Indices are
not wrapped: a negative or out-of-range index is a `ValueError`, not a
silent Python wrap-around to the opposite corner of the pupil (which is the
single easiest way to get a mirrored disparity sign downstream).
Raises `ValueError`: *lf* not a valid light field, and *v* / *u* not
an int in `[0, V) / [0, U)`.
Typed bridge of the lightfield op `lf_subaperture 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.
