Robust covariant local feature detectors are important for detecting local features that are (1) discriminative of the image content and (2) can be repeatably detected at consistent locations when the image undergoes diverse transformations. Such detectors are critical for applications such as image search and scene reconstruction. Many learning-based local feature detectors address one of these two...
Compressed sensing (CS) with prior information concerns the problem of reconstructing a sparse signal with the aid of a similar signal which is known beforehand. We consider a new approach to integrate the prior information into CS via maximizing the correlation between the prior knowledge and the desired signal. We then present a geometric analysis for the proposed method under sub-Gaussian measurements...
In the development of practical application projects, there are frequently some duplicated application modules, which may be running on different development platforms, or may be independently autonomous systems. If those application modules could be integrated into different platforms, the efficiency to utilize them would be highly improved. In this paper, the integration technology of unified architecture...
The study was to compare the characteristics of event-related potentials (ERPs) and brain topographic maps in normal group and cochlear implant (CI) group six months after device ‘switch on’. Results showed more negative N1 component by standard and target stimuli and lower P2 amplitudes were observed for the CI group. The amplitudes of MMN component were a little smaller than those of normal group...
This study explores a novel application of multiscale entropy (MSE) analysis for characterizing different patterns of spontaneous electromyogram (EMG) signals including sporadic, tonic and repetitive spontaneous motor unit discharges, and normal surface EMG baseline. Two algorithms for MSE analysis, namely, the standard MSE and the intrinsic mode entropy (IMEn) (based on the recently developed multivariate...
According to the TOP model theory, taking one tunnel as an example, the environmental effect of pollutant diffusion from tunnel portal is analyzed. The research findings show that the concentration of pollutants is beyond the ambient air quality standards in a certain region near the tunnel portal, when all of the waste gas discharges from portal without from shaft. The concentration of pollutants...
Spatial data has been extensively used in forest resource management and decision making in China. But research on spatial data sharing and interoperability in forest farm level is unavailable. This paper proposed an approach to address problems of distributed spatial data management, sharing, integration and interoperability for forest farms using OGC Web Feature Services (WFS), Web Map Service (WMS)...
With great volumes of geospatial data and data from different fields distributed across Internet, the sharing and utilization of these data have presented great challenges for research and application in geographical information science. Moreover, the new concepts and technologies of Web 2.0 represent new user demands for user-oriented interaction, and collaboration. There is an emerging need to provide...
