MORPHOLOGICAL ANALYSIS OF UO2 POWDER USING A DEAD LEAVES MODEL

In the present work, we propose a set of methods for a morphological a nalysis of powder media. To evaluate our methods, we apply them to UO2 powder. These methods are based on a Dead Leaves Model which simulate s a masking process. Generally speaking, our methods require no image segmentation. We found, that it is preferable to eliminate the segment ation approach for complex structures and to work directly on the grey level images. We compare these new algorithms with the traditional me thod of establishing the size distribution by openings, to show their relative performance.
