The concentration grade in mineral flotation is closely related to the froth texture complexity. To deal with the defects of rigid comparison of basic texture spectrum, we present a novel rotate classification fuzzy texture spectrum method for mineral separation process from engineering aspects. The frequency-statistics curve of neighborhood pixels grayscale difference is fitted by using an exponential function, and the optimal threshold value of the fuzzy internal is determined.According to the grayscale d...
