Sequence alignment is of great importance in biology research. BLAST is a sequence alignment tool used extensively by researchers. However the continuously increasing amount of sequence data to be processed presents many challenges to it. This paper gives a simple and effective approach to parallelizing BLAST using the MapReduce technique. The MapReduce-BLAST shows very good performance and scales...
Dynamic texture is a spatially repetitive, time-varying visual pattern that forms an image sequence with some spatio-temporal stationary properties. This paper proposes a dynamic texture classification algorithm based on the magnitude information and the phase information in dual-tree complex wavelet transform domain. The variance and entropy of the complex wavelet coefficients are used to form the...
Texture classification plays an important role in image analysis. The wavelet transform is a very efficient multiscale analysis method that has been successfully applied to describe the texture. The double-density dual-tree wavelet transform can simultaneously possess the properties of the double-density discrete wavelet transform (DWT) and the dual-tree DWT. In this paper, the texture feature based...
The software industry and most multinational IT companies are starving for software engineers who can write high quality codes. Universities and colleges, being the most important educational institutions, should of course shoulder the burden to cultivate such qualified software engineers. Many methods have been explored to make this educational task more efficient. Peer code review (PCR) is such...
