Our work focuses on the analysis of human full-body movement for animating a virtual agent, called Greta, able to perceive and interpret users’ expressivity and to respond properly. Our system takes in input video data related to a dancer moving...

Here, the important issue is not the learning of a complex skill, but determining the copying fidelity of animals at different l...
