Otherness feature extraction method for underground image based on Shearlet transform
Gong-kuang zidonghua, 2016 For the problem that face images collected underground are susceptible to dust interference and most feature extraction methods are sensitive to noise, an otherness feature extraction method for underground image based on Shearlet transform was proposed.
