class data_juicer.ops.filter.VideoMotionScoreFilter(min_score: float = 0.25, max_score: float = 1.7976931348623157e+308, sampling_fps: float[float] = 2, size: int[int] | Tuple[int[int]] | Tuple[int[int], int[int]] | None = None, max_size: int[int] | None = None, relative: bool = False, any_or_all: str = 'any', *args, **kwargs)

Bases: Filter

Filter to keep samples with video motion scores within a specific range. The Farneback’s algorith from OpenCV is used to compute dense optical flow.

__init__(min_score: float = 0.25, max_score: float = 1.7976931348623157e+308, sampling_fps: float[float] = 2, size: int[int] | Tuple[int[int]] | Tuple[int[int], int[int]] | None = None, max_size: int[int] | None = None, relative: bool = False, any_or_all: str = 'any', *args, **kwargs)

Initialization method.

Parameters:

• min_score – The minimum motion score to keep samples.

• max_score – The maximum motion score to keep samples.

• sampling_fps – The sampling rate in frames_per_second for optical flow calculations.

• size – Resize frames before computing optical flow. If size is a sequence like (h, w), frame size will be matched to this. If size is an int, smaller edge of frames will be matched to this number. i.e, if height > width, then frame will be rescaled to (size * height / width, size). Default None to keep the original size.

• max_size – The maximum allowed for the longer edge of resized frames. If the longer edge of frames is greater than max_size after being resized according to size, size will be overruled so that the longer edge is equal to max_size. As a result, the smaller edge may be shorter than size. This is only supported if size is an int.

• relative – If True, the optical flow magnitude is normalized to a [0, 1] range, relative to the frame’s diagonal length.

• any_or_all – keep this sample with ‘any’ or ‘all’ strategy of all videos. ‘any’: keep this sample if any videos meet the condition. ‘all’: keep this sample only if all videos meet the condition.

• kwargs – extra args
