Single precision floating point matrix multiplier using low power arithmetic circuits
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
The main objective of this thesis work is to implement a Single Precision Floating Point Matrix Multiplier with the help of basic low power arithmetic circuits. Such circuit can be used in various digital signal processing, ...
Spectro-temporal features based automatic speech recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
ASR technology has found its application in almost every field in life. Today‟s world cannot be considered as noise-free and deploying ASR technology in such environments would incorporate the challenge to deal with various ...
Spectrum sensing in cognitive radio using quickest change detection framework
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Spectrum sensing is a term associated with detection of primary (licensed) users
(PU) by secondary (unlicensed) users (SU) to pursue opportunistic transmission
of their data. The problem of spectrum sensing is challenging ...
Study of communication schemes for multiple neural processing nodes
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Over the past few years variety of hardware for implementing Artificial Neural
Networks (ANN) has been designed. The most basic approach to speed up any
ANN algorithm, is to parallelize processing. However, the existing ...
Study of fuzzy clustering algorithms and enhanced fuzzy reasoning application to texture based image segmentation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
c-means (k-means) is a popular algorithm for cluster analysis. Many variants of
c-means algorithms are available. All these models are studied in depth and convergence
of iterative solutions are verified, in this thesis. ...
Summarizing medical texts for effective retrieval
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
User centered health information retrieval is a challenging and important problem
in information retrieval. In this work, we apply medical resources to bridge the
vocabulary mismatch between lay-users and medical documents. ...
Wideband active mixer with high gain and high linearity
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
An active mixer is presented with improved conversion gain and linearity over
a wide range of frequency. The mixer is combined with a low noise amplifier
which not only provides braodband input matching but also cancels ...
Binarizing degraded document image for text extraction
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
The recent era of digitization is expected to be digitized many old important documents
which are degraded due to various reasons. Binarizing Degraded Document Image for
Text Extraction is a conversation of document color ...
Road detection for intelligent transport systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Road detection is an important machine vision problem with applications to driver
assistance systems and autonomous vehicles. We carried out a literature survey
of the state of the art road detection algorithms. Simulations ...
Text retrieval from the degraded document images
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Image binarization is used to obtain a black and white text document from a colored
one. Basically, it can be taken as an image segmentation task that segments
the text part from the background. Such a black and white ...
