decode op• 資料種類:lightfield → table
• 呼叫: import fullseye as fs; fs.ledger.lf_stats(lf)(要直接呼叫實作,import lightfield; lightfield.lf_stats(lf);從台帳取用則 opslightfield.get("lf_stats"))
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.
