Special invitation to graduate students : Graduate students are invited to present posters on their master or Ph.D. work during the conferences VI/QCAV'99 (Vision Interface and Quality Control by Artificial Vision). These posters will not be reviewed, however, the best presentations will be awarded. The list of the posters will appear in the proceedings of the conferences. The two conferences aim to gather academic researchers and industrial partners, this will offer the opportunity for students to meet these participants.
