Design of metamaterial
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)Meta materials are artificially designed materials that exhibit very high transmission values within a frequency range. Double Negative (DNG) Meta material shows both negative permittivity and negative permeability within ... -
Human action recognition in video
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)Action recognition is a central problem in computer vision which is also known as action recognition or object detection. Action is any meaningful movement of the human and it is used to convey information or to interact ... -
Mobility models and its application in ad-hoc network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)The Performance of MANET application depends on several parameters like no. of nodes, node density, communicating traffic pattern, communication range of a node, routing protocol, battery power of a node, mobility etc. ... -
Moment based image segmentation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)Usually, digital image of scene is not same as actual; it may degrade because of environment, camera focus, lightening conditions, etc. Segmentation is the key step before performing other operations like description, ... -
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 ... -

It captures geometrical smoothness along multiple directions and ... -
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 ... -
Super-resolution of hyperspectral images
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)Hyperspectral (HS) images are used for space areal application, target detection and remote sensing application. HS images are very rich in spectral resolution but at a cost of spatial resolution. HS images generated by ... -
Use of collaborative filtering for targeted advertising
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)Often in our daily life, we come across situations when we have many options available and are expected to choose one of them. May it be a bookstore, CD shop or a shopping store, even on the internet, the availability of ...
