Summary: | This paper describes a novel multilayer image classification method based on a nuclear norm of dictionary atoms minimization; in each layer, the method designs dictionary atoms for training dataset by solving a nuclear norm regularized convex optimization problem. The problem promotes non-orthogonality of dictionary atoms and makes coefficient vectors non-negative; these contribute to the improvement of classification accuracies. Experiments result shows that our method is superior to the conventional KLT (Karhunen-Loéve Transform) based multilayer classification method in classification accuracy. |
