Recently, image set representation and classification is an important problem in computer vision and pattern recognition area. It has been widely used in many computer vision applications. In this paper, a new image set representation method, named covariate-relation graph (CRG), has been proposed. CRG aims to represent image set with a graph model. Compared with existing representation methods, CRG...
Safety requirement is the most important issue for operators in the filed of nuclear science, especially material processing within shielded radioactive manufacturing environment under which material processing needs a great of manual operations and any operation mistake would cause to permanent radiation threat to body of operators and loss of enormous economical value. This paper proposes a novel...
Nowadays in order to process and store many kinds of multimedia data, the storage capability of memory has grown greatly. Moreover the widespread use of mobile devices and cloud computing has made criminal investigators often face a lot of memory dumps. They have to deal with a large quantity of memory data and complex OS data structures which they have little knowledge of. How to analyze memory evidence...
Port hopping is a typical moving target defense, which constantly changes service port number to thwart reconnaissance attack. It is effective in hiding service identities and confusing potential attackers, but it is still unknown how effective port hopping is and under what circumstances it is a viable proactive defense because the existed works are limited and they usually discuss only a few parameters...
As one of the fundamental courses in computing curriculum, the course construction of operating systems is important and difficult. In this paper, we pro-posed an innovative framework for teaching operating system with practical operating system which emphasizes on the effective combination of theoretical teaching and experimental teaching. What's more, the framework can be customized and tailored...
A 5-parameter bundle adjustment method is proposed in this paper for global mosaic of an image sequence. By decomposing the rotation matrix into a 3-parameter rotation axis and a rotation angle, to each image, there are 5 parameters that need estimate for rotation axis, rotation angle and focal length. The proposed method minimizes the distance between feature matches in 3D space so that these 5 parameters...
In this paper, a descreening algorithm based on wavelet is given. Wavelet decomposition is used to eliminate the halftone noise while preserving most of the original image contents. First, convert the color image to color space CMYK with the linear transformation. Then design the corresponding filter according to the direction of each channel after wavelet decomposition. Furthermore, optional nonlinear...
