摘要： Computer-implemented methods and computer program products for automatically transferring expressions between rigs with consistent joint structure, and for automatically transferring skin weights between different skin meshes based on joint positioning. A method is provided for transferring an expression between a source rig and a target rig, where each rig characterizes an animated character, and each rig, in turn, is characterized by a set of joints and a skin mesh having a plurality of vertices, with each vertex characterized by a matrix of weights relating a response of the vertex to movement of associated joints. A set of offsets is calculated of joint positions of a goal expression of the source rig relative to a neutral expression of the source rig. A scaling transformation is then applied to the set of offsets to produce a scaled set of offsets, which are added, in turn, to a neutral expression of the target rig. Methods are also provided for transferring a set of skin weights between a source rig and a target rig.

摘要： A method and system for driving a graphical object based on a performance of an actor in a video stream. A plurality of key frames are selected in a calibration video stream, allowing animation control values to be defined, in accordance with artistic intent, for each of a set of control variables, corresponding to each of the key frames. Features of the actor in the calibration video stream are parameterized so as to obtain a vector of values of parameters for each frame of the calibration video stream, and, then, an array of distance vectors is derived, characterizing a distance between each pair of vectors of values of parameters among the video stream frames. The space of distance vectors is mapped into the set of control variables according to a mapping operation which is then applied to distance vectors derived from an actual performance video stream to obtain a time sequence of animation control values. Finally, an animation is created on the basis of applying the sequence of animation control values to the graphical object.

摘要： Methods and computer program code computer program codes for modifying an expression of an actor in at least one video frame based on performance of the actor in a sequence of frames of video footage. A plurality of control points are identified for characterizing the shape of the actor in each frame of the video footage by a shape vector comprising positions of the control points. The shape vectors of each frame are then warped to a common standard frame thereby generating an aligned shape vector and a transformed image for each frame. The aligned shape vectors and attendant texture vectors are transformed in accordance with specified pose and expression parameters to create new shape and texture vectors which are reinserted into the sequence of frames so as to reanimate the actor.

摘要： A system and method for cleaning a set of motion capture data, wherein the data correspond to a set of point coordinates relating to a model but may include missing or inaccurate values. A subset of the motion capture data is identified that corresponds to valid points matching locations of corresponding points of the model, and a best set of model parameters is computed in such a manner as to minimize a norm of the valid points with respect to the model. A complete set of point coordinates is then predicted based on the best set of model parameters and a subsequent set of cleaned motion capture data. Actual points are inserted where validated, and the process is iterated until a specified criterion is met.
