1. A computer-implemented method of dynamically monitoring material quality in a comminution system comprising a material crushing stage and a discharge stage, the method comprising:
capturing an image of comminuted material in the discharge stage via at least one imaging device;
extracting one or more characteristic features from the captured image for analysis with respect to at least one boundary condition; and
generating output signals corresponding to a determined comminution state of the comminuted material in the discharge stage based on the analysis with respect to the at least one boundary condition.
