Current data fusion architectures are evolving from single-platform, standalone systems to multi-platform, integrated systems. By taking advantage of the favorable geometry of a distributed data fusion system, target tracking performance can be greatly increased. Sensors can typically provide an estimation of a target's position, but only the radial component of the target's velocity. The targe...

This study attempts to establish if a significant relationship exists between dynamic range and loudness over time through the analysis of historical digitally mastered audio recordings for different genres of music. The study also attempts to establish if a significant relationship exists between the auditory perception of dynamic range and sound quality on digitally mastered audio recordings ...

Immunocytochemical markers are increasingly applied for diagnosis of diseases. Usually two or more marker stains are applied at once, together with a counterstain for a reliable microscopic investigation of cell specimens. As a preprocessing step for the detection of marker-positive cells, other stains should be removed by image processing techniques. This virtual destaining can be achieved by ...

At present, enterprises have urgent needs to conduct an effective and stable statistical analysis on big data. With a view to solving the issue of analysis and processing of big data in respect of enterprise business, this essay proposes a hybrid structure mode based on the MapReduce technology and the parallel database technology, discusses the principle on which the mode is used to realize th...

In this paper we propose a test statistic to discriminate between models with nite variance and models with in nite variance. The test statistic is the ratio of the sample standard deviation and the sample interquartile range. Both asymptotic and nite sample properties of the test statistic are discussed. We show that the test has good power properties against in nite-variance distributions and...

Detecting abnormal material properties associated with diseased tissues from images requires accurate displacement data. We examined three affine model-based methods for measuring 3D displacements in regular image sequences. The advantage of these methods is that only one or no range image is needed for the whole sequence. We demonstrate, using images of both synthetic material and real burn pa...

Query processing on road networks has been extensively studied in recent years. However, the processing of moving queries on road networks has received little attention. This paper studies the efficient processing of moving range queries on road networks. We formulate a network-based concept called safe exits that guarantee the query result of the client remains unchanged before the client reac...

This contribution evaluates the impact of chroma subsampling using two different downsampling filters using objective metric. Objective results show that distributing 4:4:4 is more efficient than its 4:2:0 counterpart for medium to high bit-rates. For low bit-rates, this increase in efficiency is reduced and in some cases even reversed.

We present a set of time-efficient approaches to index objects moving on the plane to efficiently answer range queries about their future positions. Our algorithms are based on previously described solutions as well as on the employment of efficient access methods. Finally, an experimental evaluation is included that shows the performance, scalability and efficiency of our methods. 2008 Elsevie...
