中心視點 —— 全光相機同時給出的那張普通 2-D 影像。
> 以下的詳細說明為原文 —— 摘要與標題已翻譯。
For odd `V and U` the centre is a single view and both modes return it
exactly. For an even axis the centre falls *between* two views, and this
operator does not pretend otherwise:
• `mode="average"` (default) returns the mean of the 2 (or 4) views
straddling the centre — the correctly-centred estimate for a Lambertian
scene, at the cost of a slight blur proportional to the disparity.
• `mode="nearest" returns the single view at floor((N-1)/2)`, which
is sharp but sits half an angular step off centre; every disparity
measured against it carries that half-step bias.
Returns a `(H, W)` 2-D image.
Raises `ValueError`: *lf* not a valid light field, unknown *mode*.
