data_juicer.ops.mapper.video_face_blur_mapper module

class data_juicer.ops.mapper.video_face_blur_mapper.VideoFaceBlurMapper(cv_classifier: str = '', blur_type: str = 'gaussian', radius: float = 2, save_dir: str = None, *args, **kwargs)

Bases: Mapper

Mapper to blur faces detected in videos.

__init__(cv_classifier: str = '', blur_type: str = 'gaussian', radius: float = 2, save_dir: str = None, *args, **kwargs)

Initialization method.

Parameters:

• cv_classifier – OpenCV classifier path for face detection. By default, we will use ‘haarcascade_frontalface_alt.xml’.

• blur_type – Type of blur kernel, including [‘mean’, ‘box’, ‘gaussian’].

• radius – Radius of blur kernel.

• save_dir – The directory where generated video files will be stored. If not specified, outputs will be saved in the same directory as their corresponding input files. This path can alternatively be defined by setting the DJ_PRODUCED_DATA_DIR environment variable.

• args – extra args

• kwargs – extra args

process_single(sample, context=False)
