Chirality is a universal phenomenon in molecular and biological systems, denoting an asymmetric configurational property where an object cannot be superimposed onto its mirror image by any kind of translation or rotation, which is ubiquitous on the scale from neutrinos to spiral galaxies. Chirality plays a very important role in the life system. Many biological molecules in the life body show chirality,...
Based on the difference of the gray scale and texture in the images of coal and gangue, the theory of the gray-level histogram was introduced. 5 characteristic parameters which are considered as the classification features were extracted from the gray-scale histogram. By introducing the self-organizing competitive neural network algorithm and support vector machine (SVM) algorithm, the identification...
