Abstract

Segmentation of cermets is a very important problem to solve for morphological investigations by automatic image analysis. An automatic method is proposed on SEM images (in BEC and BET modes) based on directional operations in mathematical morphology and i) a distance function, ii) a discrimination of convex grains and grain clusters, and iii) a watershed. Good results are obtained.

Keywords : directional mathematical morphology, distance function, segmentation, watershed, WC-Co cermets
