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, we present a novel 3D face recognition algorithm based on the sparse representation. First, a 3D face normalization approach is proposed to deal with the raw faces. Then, three types of facial geometrical features are extracted to describe the 3D faces. Meanwhile, in order to guarantee the feasibility of the sparse representation framework(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)
This paper proposes a new approach for generating smart 3D speech animation. The basic idea is to synthesize the animated faces using prosodic information edited by user with a kind of markup language. The proposed technique takes advantage of both performance-driven and parameter-driven approaches. So it greatly reduces the workload of manual modeling used(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)
