lf_center_view — LIGHTFIELD views op

資料種類:lightfieldimage2d

呼叫:import lightfield; lightfield.lf_center_view(lf, mode='average')(或 opslightfield.get("lf_center_view"))

用法

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*.
