recursive opvideo → videoimport fullseye as fs; fs.ledger.frame_difference_causal(video) -> 'np.ndarray' (実装を直接呼ぶなら import videostream; videostream.frame_difference_causal(video) -> 'np.ndarray'、台帳から引くなら opsvideostream.get("frame_difference_causal"))|frame t − frame t−1| with a zero first frame → (T, H, W) (video).
Same length as the input (unlike :func:videops.frame_difference, T−1),
so it composes frame-for-frame with the other stream ops.
