Dynaface measures facial symmetry and facial movement from still images and video, using AI to place 97 facial landmarks automatically. It works on both symmetric and asymmetric faces, and every measurement can be exported to CSV/Excel for further analysis.
Dynaface is free and open source, and is developed by Jeff Heaton in collaboration with Johns Hopkins University. All processing happens locally on your own machine — no image or video data is uploaded anywhere. See the story behind Dynaface for background.
Dynaface is a research tool and is not a registered medical device; see Legal for details.
