    New Features for Authentication by On-Line Handwritten Signatures

    Authentication by handwritten signature is the most accepted authentication system based on biometrics partly due to the fact that it is easy to be used and part of our cultural habits. We present some improve...

    Improving DTW for Online Handwritten Signature Verification

    Authentication by handwritten on-line signature is one of the most accepted authentication system. In a way, it is based on biometrics. It is embedded in our cultural habits and easy to use. The aim of this pa...

    A structural representation for understanding line-drawing images

    In this paper, we are concerned with the problem of finding a good and homogeneous representation to encode line-drawing documents (which may be handwritten). We propose a method in which the problems induced...

    A coarse vectorisation as an initial representation for the understanding of line drawing images

    In this paper, we are concerned with the problem of finding a good and homogeneous representation to encode line drawing documents (which may be handwritten). We propose a method in which the problems induced ...

    Control of composite material strucrure by fractal methods

    The interest of fractal geometry applied to the control of material structures is presented. It allows a fine classification linked to quality that would lead to a better managment of production. Samples are m...
