of conveyer belt. Considering the complex scene and the poor video quality of the conveyer belt, coal gangue was detected and recognized by an improved Gaussian mixture model (GMM) which extracts... discrimination ratio is 95.38%. The proposed method can effectively detect coal gangue in the coal flow on the conveyer belt, which is good for improving the quality of coal and the safe operation......
