This paper proposes a novel signature based on singular value decomposition (SVD) for video sequence matching. By considering the input image as a matrix, a partition procedure is first performed to separate the matrix into non-overlapping sub-images of a fixed size. The SVD process then individually decomposes each partitioned sub-image into an singular value and the corresponding singular vec...

This paper considers a high-resolution multiple non-stationary and non-Gaussian source localization algorithm based on the proposed generalized cumulant structure (GCS) matrix that is constructed as a weighted sum of the second and fourth order cumulants of the sensor signals. The weight determines the rank and range space of the GCS matrix, and the range space of the GCS matrix should be same ...

We give upper and lower bounds on the largest singular value of a matrix using analogues to walks in graphs. For nonnegative matrices these bounds are asymptotically tight. In particular, the following result improves a bound due to Schur. If A = (aij) is an m n complex matrix, its largest singular value satis…es 2 (A) max i2[m] P j2[n] jaij j cj max aij 6=0 ricj ; where ri = P k2[n] jaikj ; cj...

The algorithms such as RSA, ElGamal and ECC work on integers. Commutative operations integer multiplication leave these vulnerable to attack by eavesdroppers. For this reason, experts develop the concept of non-commutative algebra in public key cryptosystem adding properties groups, semirings, semiring division, matrices matrix decomposition. However, generating process some cryptosystems is qu...
