lf_stats — LIGHTFIELD decode op

• データ種: lightfield → table
• 呼び出し: import fullseye as fs; fs.ledger.lf_stats(lf) (実装を直接呼ぶなら import lightfield; lightfield.lf_stats(lf)、台帳から引くなら opslightfield.get("lf_stats"))

使い方

Describe a light field: shape, angular centre, and the slope range it can carry.

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.
