描述一個光場:形狀、角度中心,以及它能承載的斜率範圍。

Returns a dict — `angular_v / angular_u · height / width` ·
`n_views = V*U · center_v / center_u ((N-1)/2`, a half-integer
when the axis is even, so `center_is_a_view` says whether a single view
actually sits at the centre) · `min / max / mean` of the samples ·
`max_slope_px, the largest |s|` for which the extreme view is still
displaced by less than half the frame, i.e. the honest limit of what this
array can measure (`min(H, W) / max(V-1, U-1, 1)`; reported as
`float(min(H, W))` when the array has a single view in both directions,
since then no shift happens at all) · `baseline_views`, the angular span
`(V-1, U-1)` that any disparity is measured over.
Raises `ValueError`: *lf* is not a finite 4-D array within the shape
and element caps.
