Depth from defocus
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
With the recent innovations in 3D technology accurate estimation of depth is very fascinating and challenging problem. In this thesis, a depth estimation algorithm, utilizing Singular Value Decomposition to compute orthogonal ...
Asynchronous analog to digital converter
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Nowadays, asynchronous systems are becoming more popular for low power applications. Asynchronous Systems help to reduce metastability errors and clock skew errors. This thesis is about an asynchronous analog to digital ...
Fractal based approach for image segmentation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
In this thesis, we have proposed an algorithm for image segmentation, using the fractal codes. The basic idea behind this algorithm is to use fractal codes for the image segmentation. This method uses compressed codes ...
Plagiarism detection

This dissertation is on plagiarism detection.
ASIC implementation of a pipelined bitrapezoidal architecture for discrete covariance kalman filter
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
This work presents, the complete ASIC implementation of Discrete Covariance Kalman ¯lter, on a Parallel and Pipelined Bitrapezoidal Systolic Array architecture. The Kalman Filter equations are mapped on the designed ...
New learning based super resolution using contourlet transform
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
new learning based super-resolution reconstruction using contourlet transforms is proposed. contourlet transform provides high degree of directionality. It captures geometrical smoothness along multiple directions and ...
Design of a low power, high speed MAC unit
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
MAC operation is the main computational kernel in any digital signal processing architectures. MAC consumes nearly 2/3 portion of total power dissipated in a DSP block. This thesis deals with the design of a low power, ...
Investigation on spatial arrangement of transceiver arrays in free space optical communication system
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Free space optical communication (FSO) is a line of sight communication that uses lasers (as transmitter) and photo detectors (as receiver) to provide communication between two points. FSO have come about in need for greater ...
Low cost design of IFFT module for dolby AC-3 decoder
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Dolby AC-3 is a flexible audio data compression technology capable of encoding a range of audio channel formats into a low rate bit stream. AC-3 is the de facto audio standard for high-end digital consumer multimedia ...
Multiresolution fusion of satellite images and super-resolution of hyper-spectral images
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
This thesis presents a model based approach for multi-resolution fusion of the satellite images. Given a high resolution panchromatic (Pan) image and a low spatial but high spectral resolution multi spectral (MS) image ...
