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 ...
Post-processing of speech signal for prosody modification and improvement
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
The basic task of a text-to-speech (TTS) synthesis system is to obtain the correct synthetic speech signal with the help of machines corresponding to the given input text. However, the main difficulty with the TTS system ...
Ultra wide band dielectric resonator array antenna
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Wireless communication play a imported role in our daily life. Present scenario of communication, all wired ones becoming as wireless. So, to achieve efficient and affordable communication in wireless technology, compact ...
Acoustic-to-articulatory inversion: speech quality assessment and smoothness constraint
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
The ability of humans to speak effortlessly, require coordinated movements of various articulators, muscles, etc. This effortless movement contributes towards naturalness, intelligibility and speaker identity in human ...

Approaches for temporal expression recognition in hindi
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Temporal annotation of plain text is considered as a useful component of modern information retrieval tasks. In this work, different approaches for identification and classification of temporal expressions in Hindi are ...
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, ...
Circuit design for cervical dilation monitoring with time varying inductor sensor
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
A pregnant female has a 42 week long gestation period for child birth. This period is divided in three categories: preterm, term and post term. A preterm labour is a labour that happens before the 37th week but after the ...
Pose estimation from one conic correspondence
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
In this thesis we attempt to solve the problem of camera pose estimation from one conic correspondence by exploiting the epipolar geometry. For this we make two important assumptions which simplify the geometry further. ...
Implementation of high speed serial communication blocks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Serial communication is widely being used from PCs to handheld mobile phones due to very less hardware, low cost, easier design process in comparison to parallel communication. For bit by bit, reliable transmission and ...
