decode op• 数据种类:lightfield → image2d
• 调用:import lightfield; lightfield.lf_to_mla(lf)(或 opslightfield.get("lf_to_mla"))
把光场重新交织成微透镜阵列的原始帧(精确逆变换)。
> 以下的详细说明为原文 —— 摘要与标题已翻译。
Inverse of :func:lf_from_mla with `offset=(0, 0)`: the returned frame has
shape `(H*V, W*U) and puts L[v, u, t, s]` back at raw pixel
`(t*V + v, s*U + u). lf_from_mla(lf_to_mla(L), (V, U)) returns L`
bit-for-bit (verified with `np.array_equal`), which is the cheapest
possible check that the decode's index arithmetic has no off-by-one.
Raises `ValueError`: *lf* not 4-D / non-finite / over the shape and
element caps (see :func:lf_from_mla), and a raw frame whose side would
exceed `MAX_SPATIAL * MAX_ANGULAR`.
