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 ...
Detection and localization of tampering in a digital medical image using discrete wavelet transform
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Use of digital images has increased tremendously in medical science as a diagnosis
tool. It made investigation easier and quick. But at the same time it raises the
question of authenticity of the image under scrutiny. ...
