Using mathematical morphology on grey level images for powder materials
Abstract
The visible upper surface shape of powder aggregates is studied with a SEM (scanning electron microscope) using the grey levels in the images. On the one hand, some new parameters for individual analysis such as volume, surface, maximum height or number of maxima per particle are defined. On the other hand, some other parameters and functions can describe the whole powder, such as global roughness or granulometry. Those global parameters were firstly defined for topological studies. They are fitted to powders. Then, for both kinds of parameters, one has to pay attention to images borders as some particles hit the frame. The answer to this problem is different whether one works with individual or global parameters.
