Motivation The rapidly increasing number of genomes generated by high-throughput sequencing platforms and assembly algorithms is accompanied by problems in data storage, compression and communication. Traditional compression algorithms are unable to meet the demand of high compression ratio due to the intrinsic challenging features of DNA sequences such as small alphabet size, frequent repeats ...
This paper describes a method for trading oo computation for disk or network I/O by using less expensive on-line compression. By using some memory to store data in compressed format, it may be possible to t the working set of one or more large applications in relatively small memory. For working sets that are too large to t in memory even when compressed, compression still provides a beneet by ...
Detecting and localizing image manipulation are necessary to counter malicious use of editing techniques. Accordingly, it is essential distinguish between authentic tampered regions by analyzing intrinsic statistics in an image. We focus on JPEG compression artifacts left during acquisition editing. propose a convolutional neural network that uses discrete cosine transform (DCT) coefficients, w...
In a hybrid raster/vector system, two representations of the image are stored. Digitized raster image preserves the original drawing in its exact visual form, whereas additional vector data can be used for resolution-independent reproduction, image editing, analysis, and indexing operations. We introduce two techniques for utilizing the vector features in context-based compression of the raster...
By applying algebraic coding methods to the Sanger dideoxynucleotide procedure, DNA sequences of two templates can be determined simultaneously in only five reactions and data channels. A 5:2 data compression is accomplished by instantaneous source coding of nucleotide sequence pairs into one set of 5-bit block codes. A general algebraic expression, 2n-1 > or = 4f, describes conditions under wh...
In a hybrid raster/vector system, two representations of the image are stored. Digitized raster image preserves the original drawing in its exact visual form, whereas additional vector data can be used for resolution-independent reproduction, image editing, analysis and indexing operations. We introduce two techniques for utilizing the vector features in contextbased compression of the raster i...
The results of a wavelet analysis of data from discrete element modelling (DEM) simulations of samples under biaxial compression are presented. We show how a wavelet technique may be used to find the strain scales on which critical events occur and to identify regions both in space and in strain when particles in the sample undergo significant activity. The wavelet analysis indicates that most ...
T Abstract. In a hybrid raster/vector system, two representations of the image are stored. Digitized raster image preserves the original drawing in its exact visual form, whereas additional vector data can be used for resolution-independent reproduction, image editing, analysis, and indexing operations. We introduce two techniques for utilizing the vector features in context-based compression o...
