The Sign Language Dataset Compendium



MEDIAPI-SKEL is a 2D-skeleton video corpus of French Sign Language with French subtitles. The corpus consists of 368 subtitled videos produced by Média'Pi, a media company producing bilingual content with French Sign Language and written French. The corpus was produced at the Laboratoire d'informatique pour la mécanique et les sciences de l'ingénieur (LIMSI).

From the original 368 videos 135 body keypoints were extracted from every signer in every frame using OpenPose. The subtitles are time aligned to the 2D-skeleton video content. Skeleton videos in JSON format and subtitles in WebVTT format are openly available, for the original videos an agreement with Média'Pi is needed.
