Non-negative spectrogram factorization has been proposed for single-channel source separation tasks. These methods operate on the magnitude or power spectrogram of the input mixtur...
Informed coding is the practice of representing watermark messages with patterns that are dependent on the cover Works. This requires the use of a dirty-paper code, in which each ...
— In this work, we examine a family of anti-collusion codes using the principle of “Orthogonal Spreading followed by the Inverse Fourier Transform (OSIFT)” as introduced in [...
