Quaternionic Wigner-Ville distribution of analytical signal in hyperspectral imagery

Author 1: Yang LIU Author 2: Robert GOUTTE

The 2D Quaternionic Fourier Transform (QFT), applied to a real 2D image, produces an invertible quaternionic spectrum. If we conserve uniquely the first quadrant of this spectrum, it is possible, after inverse transformation, to obtain, not the original image, but a 2D quaternion image, which generalize in 2D the classical… Read full abstract & cite →

On the Practical Feasibility of Secure Multipath Communication

Author 1: Stefan Rass Author 2: Benjamin Rainer Author 3: Stefan Schauer

Secure multipath transmission (MPT) uses network path redundancy to achieve privacy in the absence of public-key encryption or any shared secrets for symmetric encryption. Since this form of secret communication works without secret keys, the risk of human failure in key management naturally vanishes, leaving security to rest only on… Read full abstract & cite →
