PDE-based denoising of complex scenes using a spatially-varying fidelity term
The widely used denoising algorithms based on nonlinear diffusion, such as Perona-Malik and total variation denoising, modify images toward piecewise constant functions. Though ed...

Computational Complexity of Itemset Frequency Satisfiability
Computing frequent itemsets is one of the most prominent problems in data mining. We introduce a new, related problem, called FREQSAT: given some itemset-interval pairs, does ther...

Optimal Pilot Symbol Distribution for Efficient and Low-Complexity Doppler-Shift and Doppler-Rate Estimation in Bursty Transmiss
— Due to relative motion between the transmitter and the receiver, the carrier of the received signal in digital burstmode transmission can be affected by Doppler distortion. Thi...
