THE USE OF MORPHOLOGICAL FILTERS IN COMPUTING DISPLACEMENT-FIELDS IN A SEQUENCE OF SEM IMAGES

In order to quantify the material deformation when submitted to mechan ical solicitations, we propose a new technique based on a set of image analysis operations. It consists in measuring the displacements of so me geometrical points selected on the surface of the deformed material and considered as landmarks. More details about this technique, prese nted below, are justified by actual applications.
