Joint analysis of medical data collected from different imaging modalities has become a common clinical practice. Therefore, image fusion techniques, which provide an efficient way of combining and enhancing information, have drawn increasing attention from the medical community. In this paper, we propose a novel cross-scale fusion rule for multiscale-decomposition-based fusion of volumetric medical...
The methodology of modeling and analyzing of a knowledge network are discussed in this article. Two steps will be taken to establish the model of a knowledge network for a scientific organization. Based no the network model, the density, betweenness centrality and structure expression analysis will be conducted. The calculation result of the density provides an objective indicator for the researchers...
Soft errors are a growing concern for computer reliability. To mitigate the effects of soft errors, a variety of software-based fault tolerance methodologies have been proposed for their low costs. Data duplication techniques have the advantage of flexible and general implementation with strong capacity for error detection. However, the trade-off between reliability, performance and memory overhead...
Soft errors are emerging as a new challenge in computer applications. Current studies about soft errors mainly focus on the circuit and architecture level. Few works discuss the impact of soft errors on programs. This paper presents a novel approach named PRASE, which can analyze the reliability of a program with the effect of soft errors. Based on the simple probability theory and the corresponding...
This paper presents a novel two-phase stereo matching algorithm using the random walks framework. At first, a set of reliable matching pixels is extracted with prior matrices defined on the penalties of different disparity configurations and Laplacian matrices defined on the neighbourhood information of pixels. Following this, using the reliable set as seeds, the disparities of unreliable regions...
