Real-Time Marker-Less Motion Capture for Animals

Real time feedback for animal movement and posture.

An updated deep learning software toolbox developed at the Swiss Federal Institute of Technology, Lausanne (EPFL) facilitates real-time feedback studies on animal movement and posture. DeepLabCut-Live! (DLC-Live!) is designed to enable computers to track and predict these factors free of motion-capture markers, by controlling or stimulating the animals' neural activity. DLC-Live!'s tailored networks predict posture from video frames, combined with low latency so researchers can supply real-time feedback and assess behavioral functions of specific neural circuits; the system also interfaces with hardware used in posture studies to deliver feedback to animals. EPFL's Mackenzie Mathis said, "It's economical, it's scalable, and we hope it's a technical advance that allows even more questions to be asked about how the brain controls behavior."   .. '
