Embodiment Construction
[0040] The 3D face animation editing and synthesis method based on motion propagation and Isomap analysis includes the following steps:
[0041] 1) The user interacts with the mouse in the projection space of the two-dimensional screen, selects the control points on the projection of the face model on the two-dimensional space for constraints, and maps the constraints specified by the user from two-dimensional to three-dimensional space, so that in three-dimensional Selected control points on the face model;
[0042] 2) After establishing the user constraints, train a prior probability model with the face animation data, estimate a multivariate Gaussian probability distribution through the training data to increase the constraints, and propagate the user constraints to the unconstrained part of the face grid, Probabilistic methods are used to select the best facial expression model for the results of motion propagation.
[0043] 3) The change of facial expression is distributed...
