Figure 7From: A comprehensive system for facial animation of generic 3D head models driven by speechAMSE ( ϵ ) and ACC ( ρ ) as a function of the number of states N and the number of mixtures M . Where (a) and (b) correspond to the case of full covariance matrices and, (c) and (d) correspond to the case of diagonal covariance matrices. The big circles indicate the best accuracy for each case.Back to article page
