Spread spectrum image steganography
IEEE Transactions on Image Processing, 1999In this paper, we present a new method of digital steganography, entitled spread spectrum image steganography (SSIS). Steganography, which means "covered writing" in Greek, is the science of communicating in a hidden manner. Following a discussion of steganographic communication theory and review of existing techniques, the new method, SSIS, is ...

Spread‐spectrum magnetic resonance imaging
Magnetic Resonance in Medicine, 2019PurposeA novel method for the acceleration of MRI acquisition is proposed that relies on the local modulation of magnetic fields. These local modulations provide additional spatial information for image reconstruction that is used to accelerate image acquisition.MethodsIn experiments and simulations, eight local coils connected to current amplifiers ...
