In this paper we present an improved Active Shape Model (ASM) for facial features extraction. The original ASM developed by Cootes et al. [1] suffers from factors such as, poor mod...

We propose a level set based variational approach that incorporates shape priors into Chan-Vese's model [3] for the shape prior segmentation problem. In our model, besides th...

The use of CAD in design makes it possible to represent complex components “as manufactured” with a great number of details. A transformation of such models into Finite Elemen...
