Abstract

The image analysis system includes an image taking unit and an image analysis unit comprising one or several image preparation modules, an analysis module for collecting characteristic image element parameter, a data processing module for collecting, storage and classification and if necessary for distributing characteristic image element parameter and for calculating characteristic quantities of the particle system homogeneity. The particles and the particle system characterizing image elements, such as gaps between secondary particles, the agglomerate or conglomerate are collected as the image elements and their parameter distribution is measured.
