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 ...
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 ...
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 ...
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 ...
High-speed 512-point FFT single-chip processor architecture
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This thesis present a fully parallel novel fixed point 16-bit word width 512 point FFT processor architecture. The 512 point FFT is realized by decomposing it into three 8 point FFT units. This approach reduces the number ...
Single frame superresolution
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Super-resolving an image from single frame observation image. In many cases more than one low resolution observations may not be available, need high spatial resolution images e.g. medical imaging, remote sensing etc.. We ...
