Practical approaches for photometric stereo
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
In this thesis work, we aim to propose approaches for photometric stereo that are less time consuming and have low computational requirements. Many applications of computer vision require high resolution 3-D structure of ...
Modeling MANETs using queuing networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Mobile Ad Hoc Networks (MANETs) are becoming an attractive solution to the services that require flexible establishment, dynamic and low cost wireless connectivity. Since nodes are mobile, routing results vary significantly ...
Statistical delay modeling and analysis for system on chip
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
It is seen that designing using conventional methodologies in Deep Sub Micron geometries, at times, ends up in very pessimistic design and less yield. This is because, today’s tools don’t consider statistical variation of ...
Study of MPLS traffic engineering with constraint-based routing
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Multi-protocol Label Switching (MPLS) is fast becoming popular for future communication networks running applications demanding high speed and Quality of Service. In this work, we have studied the evolution of MPLS, various ...
Design of low-voltage, low-power, wide-band CMOS LC VCO using active inductors
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
In this thesis the design of low-voltage, low-power, wide-band CMOS LC VCO using active inductor has been proposed. The oscillator is based upon the classic LC-tuned negative-resistance topology, with a novel active inductor ...
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 ...
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, ...
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 ...
