An image analysis technique based on mathematical morphology tools dedicated to the segmentation of X-ray tomographic images of porous media is presented in this article. It consists in an efficient denoising using alternate sequential filters and a watershed operation using an original starting marker. The image is transformed into a mosaic that is straightforward to segment. An application to building stones of heritage monuments illustrates the potentialities of this technique.
