Video compression using color transfer based on motion estimation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Many compression techniques were developed in last decade and are being used in many applications like HDTV, Videoconferencing, Videophone, multimedia work stations and mobile image communications. It is also certain that ...
Statistical co-analysis, robust optimization and diagnosis of USB 2.0 system for signal and power integrity
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Signal Integrity (SI) and Power Integrity (PI) are the most critical issues as semiconductor industry is moving towards higher operational speeds. Signal integrity and power integrity are such issues that should be looked ...
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 ...
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 ...
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 ...
Built-in self test architecture for mixed signal systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Built-in self test architecture or BIST as we call them, are the necessity of time since the shrinking sizes of component on-chip with advance in IC technology are making it BIST artistries are being rapidly developed and ...
Differential geometry and image processing
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
There are various ways of observing and interpreting images. At higher levels of abstraction, one looks at an image as collections of objects, while at the other end it is just a collection of curves and surfaces. We study ...
Effect of channel asymmetry on reputation based cooperation mechanisms in mobile ad-hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Enforced cooperation among MANET nodes is an active research issue. In applications, where the users have different goals and there is no central authority to control them, users may become selfish. These nodes may not ...
Multirate signal processing in digital communications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Fundamentals of multirate signal processing and perfect reconstruction filter banks are revisited. An attempt is made to develop a good understanding of concepts by connecting the filter bank design issues to the concepts ...
Object classification in images using information slicing
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Human visual system, in real world, identifies objects by their shapes, sizes and colors. More than often we identify objects around us specifically by using contextual knowledge of the objects. For example, an area of ...
