According to the characteristics of high flexibility, high frequency of fault and difficult to detect real-time of the UAV, fault classification model by the Back Propagation neural network based on wavelet entropy and adaptive fireworks algorithm has been proposed. The fault signal can be analyzed locally with wavelet packet entropy, then extract the feature vector, which is used to express the feature...
A face clustering method based on facial shapes is proposed in this paper. In order to improve image retrieval efficiency in large database, a modified ISODATA clustering method is used to categorize faces into different classes using facial shape features. Firstly, face images are clustered into 7 classes according to face contour; secondly, in each face contour class, facial shape features including...
Gait recognition is a relatively new subfield in biometric recognition, which attempts to recognize people from the way they walk or run. This paper discusses silhouette-based feature descriptor. Human silhouette geometry is generated by boundary tracking approach and resampled to a normalized format. Boundary-centroid distance is proposed to describe gait modality. Then, we apply wavelet transform...
Gait is a potential behavioral feature, and many allied studies have demonstrated that it can be served as a useful biometric feature for recognition. This paper described a novel gait recognition technique based on support vector machine fusion of contour projection and skeleton model features. A principal component analysis method was used to lower the dimension of contour projection after segmenting...
Effective action classify plays an important role in intrusion prevention system (IPS), especially application layers IPS. Classify is the basic in data mining tasks. Naive Bayesian classifier is widely used in data mining tasks due to its computational efficiency and competitive accuracy. For the naive Bayesian independent assumption is rarely realistic, and somehow depresses the classifierspsila...
