The problem of computing sparse (mostly zero) or sparsifiable (by linear transformation) solutions to underdetermined linear systems of equations has applications in compressed sensing and minimumexposure medical imaging. We present a simple, noniterative, low-computational-cost algorithm for computing a sparse solution to an underdetermined linear system of equations. The system matrix is the ...

In this paper, we propose a robust blind watermarking algorithm for high-definition video contents. For the security of watermark information, a matrix of random numbers is generated using a secret key. We perform inverse steerable pyramid transformation (SPT) to the matrix to produce a transformed matrix. The 2-dimensional fast Fourier transformation (2D FFT) is performed to the luminant compo...

Among the different forms of spectroscopy, nuclear magnetic resonance (NMR) shows an intimate connection between theory and experiment. NMR therefore enjoys great popularity in the development of new methods. Following the rapid development in electronic and computer technology, NMR techniques evolved from singlechannel to multi-channel and multi-dimensional modes. The original continuous wave ...

The main objective of this paper is a texture based solution to the problem of acute stroke tissue recognition on computed tomography images. Our proposed method of early stroke indication was based on two fundamental steps: i) segmentation of potential areas with distorted brain tissue (selection of regions of interest), ii) acute stroke tissue recognition by extracting and then classifying a ...

in the present work, a hybrid of fourier transform and homotopy perturbation method is developed for solving the non-homogeneous partial differential equations with variable coefficients. the fourier transform is employed with combination of homotopy perturbation method (hpm), the so called fourier transform homotopy perturbation method (fthpm) to solve the partial differential equations. the c...
