DiffeoRaptor: Diffeomorphic Inter-modal Image Registration using RaPTOR
Nima Masoumi, Hassan Rivaz, M. Omair Ahmad +1
Purpose: Diffeomorphic image registration is essential in many medical imaging applications. Several registration algorithms of such type have been proposed, but primarily for intr…
Design and Hardware Implementation of a Separable Image Steganographic Scheme Using Public-key Cryptosystem
Salah Harb, M. Omair Ahmad, M. N. S Swamy
In this paper, a novel and efficient hardware implementation of steganographic cryptosystem based on a public-key cryptography is proposed. Digital images are utilized as carriers…
Speech Enhancement in Adverse Environments Based on Non-stationary Noise-driven Spectral Subtraction and SNR-dependent Phase Compensation
