Description

This paper introduces imaging processing developed with the SPARTACUS system in the field of ultrasonic testing. The aim of the imaging processing is to detect and to separate defects echoes from background noise. Image segmentation and particularities of ultrasonic images are the base of studied methods. 4 figs.; 6 refs

Abstract (French)

Cet article presente des traitements d'images obtenus en controle non destructif par ultrasons, par l'intermediaire du logiciel SPARTACUS. Ces traitements sont developpes pour detecter et separer du bruit les echos de defauts. Les methodes employees se basent sur la segmentation d'image et sur les particularites des images ultrasonores
