Based on the assumption that low-resolution (LR) and high-resolution (HR) manifolds are locally isometric, the neighbor embedding super-resolution algorithms try to preserve the geometry (reconstruction weights) of the LR space for the reconstructed HR space, but neglect the geometry of the original HR space. Due to the degradation process of the LR image(More)
This paper proposes a novel and efficient re-ranking technque to solve the person re-identification problem in the surveillance application. Previous methods treat person re-identification as a special object retrieval problem, and compute the retrieval result purely based on a unidirectional matching between the probe and all gallery images. However, the(More)
Person re-identification has been widely studied due to its importance in surveillance and forensics applications. In practice, gallery images are high resolution (HR), while probe images are usually low resolution (LR) in the identification scenarios with large variation of illumination, weather, or quality of cameras. Person re-identification in this kind(More)
Shot is usually used as basic unit for video content analysis, content-based indexing and retrieval. In this paper, a new method of shot boundary detection based on color feature is proposed aiming to obtain accurate detection with inexpensive cost. The technique is able to detect cut shot boundaries through the analysis of color histogram differences and(More)
Instead of using probabilistic graph based or manifold learning based models, some approaches based on position-patch have been proposed for face hallucination recently. In order to obtain the optimal weights for face hallucination, they represent image patches through those patches at the same position of training face images by employing least square(More)
A novel distributed video surveillance system, called as E-touch is presented in this paper. The system provides a three-layers model based on overlay network. In the middle layer of the model, overlay service network layer (OSNL) is composed of many intelligent overlay nodes mapped by underlying network. Overlay nodes provide all kinds of media service for(More)
In kidney, the ubiquitin carboxy-terminal hydrolase 1 (UCH-L1) is involved in podocyte injury and proteinuria but details of the mechanism underlying its regulation are not known. Activation of NF-κB is thought to be the predominant risk factor for kidney disease; therefore, it is postulated that UCH-L1 may be one of the NF-κB target genes. In this study,(More)
