In this paper, we propose a novel and efficient framework for the extension of multi-scale blob detection for the color domain to prevent information loss due to gray scale transformation and to allow us to exploit the photometric information. The framework also works well in gray scale space, it is mostly composed of i) a weighted multi-scale blob detector(More)
Abandoned object detection in highway scene is one of the most crucial tasks in intelligent visual surveillance systems. However, few previous methods on abandoned object detection have focused on this important problem. In this paper, we present a new framework to detect the abandoned objects. In our framework, Gaussian mixture model (GMM) is used to model(More)
The biometrics grid can simplify resource management and access by making biometrics data as easy to access as Web pages via a Web browser. It tests user-designed modules, which are wrapped to Web services and deployed into a Web services container. Risk-resilient strategies are used for job scheduling. A case study of two biometrics recognition processes(More)
With the rapidly increasing of 3D models, the 3D model retrieval methods have been paid significant research attention. Most of the existing methods focus on taking advantage of one kind of feature. These methods can not achieve ideal retrieval results for different classes of 3D models. In this paper, we propose a novel 3D model retrieval algorithm by(More)
This paper presents a human detection approach which can process images rapidly and detect the objects accurately. The features used in our system are the cascade of the HOG (Histograms of Oriented Gradients) and LBP (Local Binary Pattern). In order to achieve high recall at each stage of the cascade, we modify the mi-SVM (Support Vector Machine for(More)
Recently, the view-based 3D model retrieval methods have received great research attentions. However, these methods are difficult to preserve the spatial structure of 3D models. In this paper, we propose a novel view-based 3D model retrieval method to solve this problem. Our method is based on the two-level (3D model-level and 2D image-level) spatial(More)
