Coal Gangue Recognition during Coal Preparation Using an Adaptive Boosting Algorithm
Minerals (Basel, Switzerland), 2023 The recognition of coal and gangue is the premise and foundation of coal gangue intelligent sorting. Adaptive boosting (AdaBoost) algorithm-based coal gangue identification has not been studied in depth. This paper proposed a coal gangue image recognition algorithm and a strong classifier based on the AdaBoost algorithm with a genetic algorithm (GA ...
