PDE Face: A Novel 3D Face Model [PDF]
, 2008 YesWe introduce a novel approach to face models, which exploits the use of Partial Differential Equations (PDE) to generate the 3D face. This addresses some common problems of existing face models.

Shape Morphing Using PDE Surfaces [PDF]
, 2006 YesA methodology for shape morphing using partial differential equation (PDE) surfaces is presented in this work. The use of the PDE formulation shows how shape morphing can be based on a boundary-value approach by which intermediate shapes can be ...

Parametric Representations of Facial Expressions on PDE-Based Surfaces [PDF]
, 2008 YesParameterisation of facial expressions on PDE surface representations of human faces are presented in this work. Taking advantage of the boundary-value approach inherent to Bloor-Wilson PDE method, facial expressions are achieved by manipulating the ...

PDE-based Facial Animation: Making the Complex Simple [PDF]
, 2008 YesDirect parameterisation is among the most widely used facial animation techniques but requires complicated ways to animate face models which have complex topology.

Fast iterative solvers for PDE-constrained optimization problems [PDF]
, 2013 In this thesis, we develop preconditioned iterative methods for the solution of matrix systems arising from PDE-constrained optimization problems. In order to do this, we exploit saddle point theory, as this is the form of the matrix systems we wish to ...

Design and analysis of propeller blade geometry using the PDE method [PDF]
, 1993 This thesis aims to incorporate geometric and functional design of surfaces using a method known as the PDE method. In particular, it will be demonstrated how the PDE method can be extended to represent an existing marine propeller geometry ...
