We present a method to measure reflectance and texture of surfaces in a one step process. For later use in digital image synthesis it is mandatory to separate the gathered intensity values into these two parts to elim...

In this paper we introduce a new mesh refinement method for subdivision surfaces. It generates a semiregular 4-direction hierarchical structure from control meshes representing 2D manifolds of arbitrary topology. the ...

One of the difficulties in pattern recognition is to develop a good evaluation of the classes presented on a scene. To suitably describe those classes it is necessary to find feature spaces which allow distinguishing ...

this paper presents a simple and robust algorithm for estimating the local geometric properties of intersection curves, namely the tangent, normal, binormal, curvature and torsion vectors at any point. In addition, tw...

Morphological residues represent an image in an hierarchical way by means of a decomposition of its structures and according to a size parameter A. From this decomposition, we can obtain a relation between the differe...
