An Image Recognition Method for Coal Gangue Based on ASGS-CWOA and BP Neural Network
Symmetry, 2022 To improve the recognition accuracy of coal gangue images with the back propagation (BP) neural network, a coal gangue image recognition method based on BP neural network and ASGS-CWOA (ASGS-CWOA-BP) was proposed, which makes two key contributions. Firstly, a new feature extraction method for the unique features of coal and gangue images is proposed ...
