Facing Document-Provider Heterogeneity in Knowledge Portals
Knowledge portals aim at facilitating the location, sharing and dissemination of information by sitting ontologies at the core of the system. For heterogeneous environments where c...

Mesh Smoothing via Mean and Median Filtering Applied to Face Normals
In this paper, we introduce iterative mean and median filtering schemes for smoothing noisy 3D shapes given as triangle meshes. Our main idea consists of applying mean and median...

Deformation Analysis for 3D Face Matching
Current two-dimensional image based face recognition systems encounter difficulties with large facial appearance variations due to the pose, illumination and expression changes. ...

Pose Invariant Face Recognition Under Arbitrary Unknown Lighting Using Spherical Harmonics
Abstract. We propose a new method for face recognition under arbitrary pose and illumination conditions, which requires only one training image per subject. Furthermore, no limitat...

The Metaphor of the Face as an Interface for Communicating Non-Quantitative Information
In this paper we propose that a metaphor can be used to represent domains that are not easily quantifiable. The metaphor then can be used as an interface to communicate informatio...
