Embodiment Construction
[0022] The present invention proposes a method for synthesizing motion of a virtual character using motion capture data based on function-based statistical analysis. Function-based statistical analysis is a statistical analysis method for time series. This method uses function-based statistical analysis to extract the index that best describes its internal change law from a given time series sample, thereby obtaining a low-dimensional function subspace. Each dimension of this space is a function, which the present invention calls "characteristic motion". The number of characteristic functions needs to be determined according to the actual problem. A certain criterion can be the error between the projection and reconstruction result of the motion data sequence and the sequence itself. This set of "feature motions" is orthogonal, and in the subspace based on the "feature motions", any motion data sequence can be projected to the "feature motions" to obtain a set of coordinate c...
