Abstract: The invention relates to a head mounted image capture device (101) for capturing facial motion of a user. The device (101) includes a helmet (102) including a front portion (103) for resting on the user's forehead, a back portion (104) for resting on the back of the user's head and side portions (105) each for resting on the sides of a user's head (H). Each side portion (105) includes a respective arm (106) which supports a respective camera (107). The device (101) also includes an articulated structure (109) connecting the front portion (103) to the back portion (104) for approximating the profile of the head (H) of the user.

Abstract: The invention relates to a method for coding animation parameters for a character (A) with which are associated morphological values, said animation parameters comprising a translation parameter associated with at least one part of said character (A), characterized in that to code an intrinsic translation of said part of said character (A) by a translation vector, said translation parameter contains a value which is dependent on said vector and on one of said morphological values.

Abstract: A method of animating a scene graph (M), which comprises steps for: creating (e1) an animation graph instance (G) comprising animation modules (MA1, . . . , MA10) and composition modules (MC1, . . . , MC4) organized in a tree structure, the animation modules being leaves of subtrees of the graph and the composition modules being used to compose results of their child modules, the latter being either animation or composition modules indiscriminately, and executing (e3) the animation by executing in turn the animation and composition modules of the graph, so that the execution of a composition module uses the results of the executions of its child modules.

Abstract: A 3D imaged head consisting of a set of meshes is animated by modelled facial muscles. For natural animation of the lips in speech, the lower and upper lips are distinguished in a set of lip mesh based on the nodes of the mesh on a boundary of the lip corner and mouth opening, and lower and upper zones of the head are divided by the boundary. Modelled muscles attached to the upper lip, with intersecting zones of influence in the upper zone, and attached to the lower lip, with intersecting zones of influence in the lower zone, displace nodes of mesh respectively in the upper lip and under the nose and in the lower lip and the chin. Other muscles have zones of influence in the lower and upper zones.
