MEDIAPI-SKEL

MEDIAPI-SKEL is a bilingual corpus of French Sign Language (LSF) in the form of pose data (coordinates of skeleton points) and French in the form of subtitles. It can be used for academic research.To constitute this corpus, we used 368 subtitled videos totaling 27 hours of LSF footage and written French produced by Média'Pi!, a media company producing bilingual content with LSF and written French .We cannot provide the original videos, which can be accessed via a subscription to Média'Pi!. We provide the French subtitles an WebVTT format, aligned with two types of data: openpose and mediapipe holistic (in version 2 of the repository), calculated from each of the videos.Data des cription:X corresponds to the number of the corresponding video, from 00001 to 00368.- Subtitles: For each X video, we provide a X.fr.vtt file containing the corresponding French subtitles.- OpenPose: For each X video, we supply a X.zip archive containing as many json files as there are frames in the video, named X_Y_keypoints.json, where Y is the frame number. Each json file contains the coordinates of 137 points (25 for the body, 2x21 for the hands and 70 for the face).- Mediapipe Holistic: For each X video, we supply a X.zip archive containing 5 csv files. X_N contains the image size (width and height), X_left_hand, X_right_hand, X_face and X_body contain the data for the hands, face and body respectively, with 1 line per frame. The 1st column shows the frame number, then for each point on the skeleton (21 for each hand, 468 for the face and 33 for the body), there is the following information: x (in pixels), y (in pixels), z (between -1 and 0), visibility (0 or 1 depending on whether the point is visible or not).Directories and files:Data directory- openpose_zips.zip- mediapipe_zips.zip- subtitles.zipInformation directory- video_information.csv: contains information about the resolution, frame rate, duration and number of frames of each video, as well as a breakdown of videos in train/dev/test sets.- example: directory containing a short extractMEDIAPI-SKEL is a 2D-skeleton video corpus of French Sign Language (LSF) with French subtitles. It can be used by members of public university and research structures.
