Based on the semantic categorization and region-based similarity measure, a novel synthetic aperture radar (SAR) image retrieval method is proposed in this paper, which is inspired by the existing content-based image retrieval (CBIR) techniques and is oriented toward the Earth observation (EO). First, due to the large sizes of SAR images, new method semantically classifies the land covers in the patch...
SAR image retrieval, lacking of well performance recently due to the particularity of SAR image, has drawn more and more attention with the increasing volume of SAR data and the dramatically enlarging application range of SAR image. This paper considers both the characteristic of content-based image retrieval (CBIR) and SAR image, proposing a novel SAR image retrieval method. The proposed method can...
This paper describes ongoing work in analyzing sensor data logged in the homes of seniors. A visualization of motion sensor data in the form of a density map which uses different colors to show levels of activity was introduced previously. For evaluating changes in activity level and periodicity of life style, we introduce a dissimilarity measurement of density maps based on co-occurrence matrices...
There is an increasing interest in uncertain and probabilistic databases arising in application domains such as sensor networks, information retrieval, mobile object data management, information extraction, and data integration. A range of different approaches have been proposed to find the frequent items in uncertain database. But there is little work on processing such query in distributed, in-network...
The deficiency in practical work of traditional IDEF0 function-modeling method is discussed. And then the IFEF0 method is improved in three aspects, and a new method named improved IDEF0 method is presented. The meaning, characteristics, and the researching idea of Efficient Support (ES) are introduced, and the function model of Efficient Support System (ESS) is given which is established by the Improved...
Kashin-Beck disease (KBD) is a chronic, endemic osteochondropathy in China. cDNA microarray techniques were used to select the differentially expressed genes between the healthy and KBD patients. 227 differently expressed genes were used to identify common characteristics. By using GeneMerge anaysis, the common functions of these genes were identified and some of which are related to metal ion binding,...
With the digital technology developments, Digital Cinema outperforms traditional films and attracts the movie industry. The first edition Digital Cinema System Specification was released by Digital Cinema Initiatives, LLC (DCI) in 2005, which advances the Digital Cinema development. We have developed a Digital Cinema Playback system compliant with the DCI Specification. It can extract and play the...
Data from projects worldwide show that many software projects fail and most are completed late or over budget. Unit testing is a simple but effective technique to improve software in terms of quality, flexibility, and time-to-market. A key idea of unit testing is that each piece of code needs its own tests and the best person to design those tests is the developer who wrote the software. However,...
A parallel belief propagation algorithm for decoding low-density parity-check (LDPC) codes is presented in this paper based on Compute Unified Device Architecture (CUDA). As a new hardware and software architecture for addressing and managing computations, CUDA offers parallel data computing using the highly multithreaded coprocessor driven by very high memory bandwidth GPU. The parallel decoding...
