نویسندگان

چکیده

Identification of coal and gangue is one the important problems in industry. To improve accuracy identification mining process, a method based on histogram oriented gradient (HOG) combined with local binary pattern (LBP) features improved support vector machine (SVM) was proposed. First, according to actual underground working environment mine, vision platform for built image acquisition experiment carried out. Then, images were denoised by median filtering, extracted using HOG LBP feature extraction algorithm, these normalized principal component analysis (PCA) reduced dimension remove correlation redundancy between features. Finally, SVM, SVM optimized genetic algorithm (GA-SVM), particle swarm optimization (PSO-SVM) grey wolf (GWO-SVM) used as classifiers classification, respectively. The experimental results show that GWO-SVM classification model has highest accuracy, average accuracies 96.49% 94.82% training set test set, respectively, which shows optimize good effect images, proves feasibility proposed method.

A Method for Surface Reconstruction Based on Support Vector Machine

Surface reconstruction is one of the main parts of reverse engineering and environment modeling. In this paper a method for reconstruct surface based on Support Vector Machine (SVM) is proposed. In order to overcome the inefficiency of SVM, a feature-preserved nonuniform simplification method is employed to simplify cloud points set. The points set is reduced while the feature is preserved afte...

A new pedestrian detection method based on combined HOG and LSS features

Pedestrian detection is a critical issue in computer vision, with several feature descriptors can be adopted. Since the ability of various kinds of feature descriptor is different in pedestrian detection and there is no basis in feature selection, we analyze the commonly used features in theory and compare them in experiments. It is desired to find a new feature with the strongest description a...
