Research Activity

My current research interest is in animal and human shape and pose estimation from images and videos. My main contribution to the field is the exploration of realistic 2D and 3D models of body shape for estimating pose and articulated motion in unconstrained images, videos, and from 3D data. In the past I have worked on color imaging and reproduction, in particular on the readability of colored text on colored background and on multispectral print.
