Efficiency in Computing Correlation Matrix of Wavelet Coefficients by Exploiting Index Structure
Correlation matrices are ubiquitous throughout signal processing, networking and in many areas of science. However, our study of the literature found that there is limited research...

Shape Matrices as a Mixed Shape Factor for Off-line Signature Verification
Shape matrices have been used as a representation of planar shapes like industrial parts or printed characters. In this paper, we investigate the use of shape matrices as a mixed ...

Deterministic constructions of compressed sensing matrices
Compressed sensing is a new area of signal processing. Its goal is to minimize the number of samples that need to be taken from a signal for faithful reconstruction. The performan...

New quasi-symmetric designs constructed using mutually orthogonal Latin squares and Hadamard matrices
Using Hadamard matrices and mutually orthogonal Latin squares, we construct two new quasi-symmetric designs, with parameters 2 (66, 30, 29) and 2 - (78, 36, 30). These are the fir...

Binary Positive Semidefinite Matrices and Associated Integer Polytopes
We consider the positive semidefinite (psd) matrices with binary entries. We give a characterisation of such matrices, along with a graphical representation. We then move on to co...
