Abstract : On a microscopic scale, a pyrotechnic material is made of a po lymer matrix containing grains with different sizes and shapes. Its physical behaviour can be predicted by homogenization. Information about the morphology of the grains can be obtained by different ways. O ne of these ways is 3D image processing. This has been made easier by the use of a new imaging technique , the microtomography, allowing fast three- dimensional reconstruction and processing. In this paper i mages of two granular materials are segmented by means of 3D mathematical morphology algorithms, based on a m ulti-scale extraction of markers for watershed segmentation.
