Recognition Methods for Coal and Coal Gangue Based on Deep Learning [PDF]

open access: yesIEEE Access, 2021
Recognizing coal and coal gangue is an important part of the coal industry and is mainly conducted via human sorting at present. Consequently, considerable manpower is needed, which adds a burden to enterprises and results in low efficiency. As an important branch of artificial intelligence, deep learning has been widely applied in many fields ...
