On a Watermarking Scheme in the Logarithmic Domain and its Perceptual Advantages
Scaling attacks are well-known to be some of the most harmful strategies against quantization-based watermarking methods, as they can completely ruin the performance of the waterm...

A DSP-based fuzzy system for real-time interference cancellation in DS-SS systems
This work demonstrates that high-end classical programmable digital signal processors (DSPs) can implement fuzzy systems for real-time communication processing. A systematic proce...

Sampling in practice: is the best reconstruction space bandlimited?
Shannon's sampling theory and its variants provide effective solutions to the problem of reconstructing a signal from its samples in some "shift-invariant " space, ...

Coded Strobing Photography: Compressive Sensing of High Speed Periodic Videos
—We show that, via temporal modulation, one can observe and capture a high-speed periodic video well beyond the abilities of a low-frame-rate camera. By strobing the exposure wit...
