video_cube_cut — VIDEOCUBE cube op

• Data kinds: video → image2d

• Call: import fullseye as fs; fs.ledger.video_cube_cut(video, plane: 'str' = 'xt', position: 'float' = 0.5) -> 'np.ndarray' (to call the implementation directly, import videocube; videocube.video_cube_cut(video, plane: 'str' = 'xt', position: 'float' = 0.5) -> 'np.ndarray'; from the registry, opsvideocube.get("video_cube_cut"))

Usage

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

立方体の断面 1 枚(`image2d)。"xt" = 行 position のスリットスキャン (T, W)、"yt"` = 列の (T, H)、

`"xy" = 時刻 position のフレーム (H, W)。position` は [0, 1] の割合(行・列・時刻の何割目か)。

x–t 断面では、右へ動く物体は右下がりの筋、止まっている物体は縦の帯になる —— 速度が傾きとして読める。

>>> streak = video_cube_cut(clip, "xt", position=0.4) # 4 割目の行を横切ったものの記録
