Data scientistMay 2022 - July 2022 (2 months)Paris, FranceThe objective was to create a model to analyze videos and detect and classify LSF (French Sign Language) signs.First, I developed an annotation application in Python for annotators to indicate the sign and the frames of the sign.Second, I trained various Deep Learning models, inspired by different papers. I then compared these models using several metrics.Finally, I deployed a Flask app so the client could test our models from their location with their own videos.
