Abstract     Image analysis has been used as a potential tool for the characterization of the texture of ultramacroporous foams prepared by freeze-drying. It has been shown that this technique actually provides valuable information on the structure of this kind of material. Image analysis of SEM micrographs of transverse cross-sections at two different magnifications gave information on both the macroporosity (1 micro m < width <10 micro m) and ultramacroporosity (width > 10 micro m). Moreover, the foam anisotropy can be detennined by image analysis of longitudinal cross-sections.
