Image acquisition in many biomedical imaging modalities is corrupted by Poisson noise followed by additive Gaussian noise. Maximum Likelihood Estimation (MLE) based restoration methods that use the exact Likelihood ...

Non-malleable codes(NMC) introduced by Dziembowski, Pietrzak and Wichs in ITCS 2010, provide powerful security guarantees where error-correcting codes can not provide any guarantee: a decoding of tampered codeword is ...

Deferred freeing is the fundamental technique used in Read-Copy-Update (RCU) synchronization technique where reclamation of resources is deferred until the completion of all active RCU read-side critical sections. We observe ...

Bilinear pairing defined over elliptic curve group was first used to design novel cryptosystem in 2000. Since then a large number of cryptosystems has been proposed in pairing-based cryptography (PBC). The main tool for ...

Transmission of bulk electric power from the generating stations to the load centres can be carried out only through high voltages transmission lines. One of the main issues in the design and maintenance of extra and ...

Visual speech recognition (VSR), or automatic lip-reading, is the task of extracting speech information from visual input. The addition of visual speech has been shown to improve the performance of traditional audio ...

We consider the problem of reconstructing a 3D surface from its multiview scans. Typically, the computational pipeline for this problem has two phases: (I) finding point-to-point correspondences between overlapping scans, ...

Due to a variety of crucial bene fits, enterprises outsource their data to cloud resident storage. The outsourced data needs to be stored in encrypted form on remote untrusted servers to preserve privacy. However, if the ...

Beamforming is a family of algorithms and performs a spatial filtering operation that makes it possible to map the distribution of the sources at a certain distance from the microphones and therefore locate the ...

Increase in the usage of smartphones and growing demand for data have resulted in congestion in the RF spectrum. To ease the overcrowding of RF spectrum, there is a need for wireless communication systems that can ...
