    Abstract: A method of animating a digital character according to facial expressions of a user, comprising the steps of, (a) obtaining a 2D image and 3D depth map of the face of the user, (b) determining expression parameters for a user expression model so that a facial expression of the user-specific expression model represents the face of the user shown in the 2D image and 3D depth map (c) using the expression parameters and an animation prior to determine animation parameters usable to animate a digital character, wherein the animation prior is a sequence of animation parameters which represent predefined animations of a digital character (d) using the animation parameters to animate a digital character so that the digital character mimics the face of the user.

    Abstract: Techniques are disclosed for creating avatars from image data of a person. According to these techniques, spatial facial attributes of a subject may be measured from an image representing the subject. The measured facial attributes may be matching to a three-dimensional avatar template. Other attributes of the subject may be identified, such as hair type, hair color, eye color, skin color and the like. For hair type, hair may be generated for the avatar by measuring spatial locations of hair of the subject and the measured hair locations may be compared to locations of hair represented by a plurality of hair templates. A matching hair template may be selected from the plurality of hair templates, which may be used in generating the avatar. An avatar may be generated from the matching avatar template, which may be deformed according to the measured spatial facial attributes, and from the other attributes.
