We present a geometric optimisation framework that can recover fold-over free maps from non-injective initial states using popular flip-preventing distortion energies. Since flip-preventing energies are infinite for folded configurations, we propose a new ...

In this paper, we describe a parametric mixture model for modelling the resonant characteristics of the vocal tract where Gaussian distributions are used to model spectral frequency regions. A mixtures of Gaussian (MoG) based parametrisation scheme is ...

For rationally fibred surfaces over Q and also over R, an effective algorithm exists that decides if such a surface has a proper parametrisation. This algorithm uses a diagonalised form of the surface equation. We show, using recent algorithms for ...
