A novel approach to classify the flotation froth images based on OLPP and support vector machine is presented to deal with the problem that the texture feature vectors of digitized images of the froth obtained from the use of gray-level dependence matrix method can not provide a compact representation of froth properties. The texture feature vectors from OLPP is transformed
and then
classification is investigated by using a multi-class SVM. Results obtained encourage to apply the approach to develop a classification system for flotation froth images. Comparison between OLPP with SVM and PCA with nearest neighbor classifier shows that the proposed recognition technology has higher precision and robustness.
