The widespread usage of digital videos calls for an intense need of video compression techniques to conserve storage space and minimize bandwidth utilization. Discrete wavelet transform (DWT) has manifested its intrinsic multiresolution and scalability advantages on image compressions without the annoying blocking artifacts. Thus, Motion estimation and motion compensation (MEMC) combined with w...

ProtoNet is an agglomerative binary clustering procedure that provides a hierarchical tree of over 1,000,000 proteins. In this paper we show that the ProtoNet tree is composed of a large number of biologically valid clusters and that the tree expresses functional information. We confirm that several aspects of the tree highly correspond to various external sources, some of which are manually va...

BACKGROUND The existing techniques for simultaneous encryption and compression of images refer lossy compression. Their reconstruction performances did not meet the accuracy of medical images because most of them have not been applicable to three-dimensional (3D) medical image volumes intrinsically represented by tensors. METHODS We propose a tensor-based algorithm using tensor compressive se...

We present a simple sentence compression approach for our summarizer based on latent semantic analysis (LSA). The summarization method assesses each sentence by an LSA score. The compression algorithm removes unimportant clauses from a full sentence. Firstly, a sentence is divided into clauses by Charniak parser, then compression candidates are generated and finally, the best candidate is selec...

Success of multimedia applications demand on-line transmission of image data. This demands online compression/decompression of image data files. Spatial redundancy of an image data file are detected and removed with a simple and elegant scheme that can be easily implemented on a compression algorithm. Compression hardware having throughput that can match the capacity of high-speed data communic...

geometric and material nonlinear behavior of slender webs in i-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. in addition, the effects of flange and web slenderness rati...
