Enhancement of microscopy mineral images through constructing alternating operators using opening and closing based toggle operator

Enhancing microscopy mineral images to produce a clear image is important for mineral analysis. In this paper, an algorithm for mineral image enhancement through the constructed alternating operators using opening and closing based toggle operators is proposed. First, the alternating operators constructed using opening and closing based toggle operator and the procedure of feature extraction are discussed. Second, the mineral image features for enhancement are extracted through the entropy based weight strategy. Finally, the mineral image is enhanced utilizing the contrast enhancement method, by combining the extracted bright and dark mineral image features. Experimental results on mineral images obtained from different microscopes under different environments verified the effective performance of the proposed algorithm, and the performance was better than some existing algorithms. Therefore, the proposed algorithm may be effectively used for different microscopy mineral image based applications.
