In this paper, a novel face representation approach, Haar Local Binary Pattern histogram (HLBPH), is proposed to represent the face images. First, the face image is decomposed into four-channel subimages in frequency domain by Haar wavelet transform, and then the LBP operator is applied on each subimage to extract the face features. After that, a novel Haar(More)
—In this paper, a novel 3D face recognition algorithm based on facial profile information is presented, which needn't the training phase, and consumes little computation cost. We first extract and normalize the 3D face profiles, and then, the shape and texture information of the profiles are used to represent 3D faces. After that, three representations and(More)
Vehicular Ad Hoc Network (VANET) is a recently developed technology to achieve traffic safety and efficiency purposes through inter-vehicle communications, where the routing protocols in VANETs play a very important role. However, one that fits all kinds of scenarios and applications does not exist for now. Insufficient forwarding nodes and network(More)
The quasi-sliding-mode control based on non-linear surface which has variable damping characteristic is proposed for discrete-time systems with uncertainty which is boundary or slow time-variant. The strategy could ensure reduce the region of quasi-sliding mode, improve dynamic quality. The control chattering and steady-states chattering are avoided.(More)
Automatic nodes location is a key supporting technology in WSN, and gains much more attention with the development of the modern network technology and wireless communication technology. In this paper, a novel locating method based on correlation analysis is presented. First, in order to get the accurate and valid data, the normalization procedure is(More)
