volseq_interpolate_flow — LIVE4D time op

• Data kinds: volseq → volseq

• Call: import fullseye as fs; fs.ledger.volseq_interpolate_flow(volseq, factor: 'int' = 2, win: 'int' = 3, pyr_levels: 'int' = 3, iters: 'int' = 5, reg: 'float' = 0.001, occlusion_tau: 'float' = 1.0) -> 'np.ndarray' (to call the implementation directly, import live4d; live4d.volseq_interpolate_flow(volseq, factor: 'int' = 2, win: 'int' = 3, pyr_levels: 'int' = 3, iters: 'int' = 5, reg: 'float' = 0.001, occlusion_tau: 'float' = 1.0) -> 'np.ndarray'; from the registry, opslive4d.get("volseq_interpolate_flow"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

体積時系列 `(T, Z, Y, X) を 3 次元の流れで補間して (T + (T − 1)(factor − 1), Z, Y, X) に(volseq`)。

`video_interpolate_flow と同じ手順の 3 次元版(流れは vol_flow_3d`)。ライトシートの z-stack は

時間方向が粗い(1 体積に秒単位)ので、ここを埋めると「回しながら動く」動画になる。
