Microscopy mineral image enhancement based on improved adaptive threshold in nonsubsampled shearlet transform domain
In this paper, a novel microscopy mineral image enhancement method based on adaptive threshold in non-subsampled shearlet transform (NSST) domain is proposed. First, the image is decomposed into one low-frequency sub-band and several high-frequency sub-bands. Second, the gamma correction is applied...
