Application of compressive sensing to tow-way relay channel estimation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
An Amplify and Forward Two-Way Relay Network is one where two nodes transmit data to
each other via an intermediate relay. The relay amplifies the superimposed data from both
the nodes before sending it to both the nodes. ...
Automatic image inpainting for the facial images of monuments
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Image inpainting is the process of restoring or modifying the image contents im-
perceptibly. In this paper we propose a novel approach for automatic image inpainting
of the ruined frontal face images of monuments or ...
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 ...
Design & layout of a low voltage folding & interpolation ADC for high speed applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC) plays a vital role
in mixed analog signalling, communication and digital signal processing world. Now a day,
the demand for designing of high ...
Disparity estimation by stereo using particle swarm optimization and graph cuts
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Stereo vision is based on the process of obtaining the disparity from a left and a right view of a scene. By obtaining the disparity, we find the distance (depth) of each object point from the camera so that we can construct ...
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 ...
FPGA implementation of multiband and multimode modem for software defined radio (SDR)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Now a days Software Defined Radio(SDR) is becoming popular for wireless communication
because of it’s flexibility to change as per requirement through software. The work presented
here describes the different methods of ...
Image ranking based on clustering
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
In a typical content-based image retrieval (CBIR) system, query results are a set of images sorted
by feature similarities with respect to the query. However, images with high feature similarities to the query may be very ...
Locality preserving projection: a study and applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Locality Preserving Projection (LPP) is a recently proposed approach for dimensionality
reduction that preserves the neighbourhood information and obtains a subspace that best
detects the essential data manifold structure. ...
