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 ...

This work discusses an ongoing project for hands gesture recognition in computer vision systems. The proposed approach is based on the shape analysis tools introduced in [1]. More specifically, the wavelet transform w...

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 ...

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...

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...

This technical poster studies the advantages and disadvantages of Fractal image Compression (FIC) compared to Wavelet Transform Compression (WTC). Our results indicate that there is an advantage in FIC for high compre...
详细信息
In this paper we present a new approach which integrates the T-Snakes model and a multi-resolution method in a unified framework for segmentation and boundary extraction. In a first stage, a local scale property of th...
