Object-background segmentation from video
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Fast and accurate algorithms for background-foreground separation are an essential part of
<p/>any video surveillance system. GMM (Gaussian Mixture Models) based object segmentation
<p/>methods give accurate results for ...
Ontology alignment based support for searching LOD-datasets using SPARQL query
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
The Linked Open Data (LOD) cloud is rapidly becoming the largest interconnected source of structured data on the web. Due to distributed nature of LOD and a growing number of ontologies and vocabularies used in LOD ...
Study and analysis of primary database operations using single node hadoop cluster
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
MapReduce framework and Hive query language are widely used for large data processing in Hadoop system. Nowadays media, corporates and government organizations are generating a very large amount of raw data. This rises new ...
Ultra wide band dielectric resonator array antenna
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Wireless communication play a imported role in our daily life. Present scenario of communication, all wired ones becoming as wireless. So, to achieve efficient and affordable communication in wireless technology, compact ...
Acoustic-to-articulatory inversion: speech quality assessment and smoothness constraint
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
The ability of humans to speak effortlessly, require coordinated movements of various articulators, muscles, etc. This effortless movement contributes towards naturalness, intelligibility and speaker identity in human ...
Microwave imaging of a 36-cell human body by moment method formulation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Estimation of a complex permittivity is achieved using the moment method formulation of electric field integral equation. In addition to numerical results for three dimensional biological bodies, thesis also describes ...
Active sub-harmonic mixer
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
A superheterodyne receiver is commonly used receiver, but its main problem is its large
size. To increase the integration and reduce the size of the receiver, the concept of direct
conversion receiver came in the picture. ...
All-digital time based analog-to-digital converter and time-to-digital converter
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
The goal of this thesis is to design a fully digital sensor interface. For this, a
time-based analog to digital converter and time to digital converter has been investigated.
It is concluded that fully digital time-based ...
Analysis of nonlinearity in speech production mechanism for speaker verification: phase-based approach
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Many of the real-world signal processing problems can be described using linear models, and can be realized as analog or digital filter, time-invariant filters; finite or infinite impulse response (IIR or FIR) filters. In ...
Application of network coding in wireless sensor and relay based ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Network Coding (NC) is a new area which brings radical change in the way we
treat information flow in networks. NC considered being a layer 3 operation has been
shown to improve the throughput of wired networks especially ...
