Image Reconstruction Based On Hilbert And Hybrid Filtered Algorithms With Inverse Distance Weight And No Backprojection Weight
(2014-07-16)
Filtered backprojection (FBP) reconstruction algorithms are very popular in the field of X-ray computed tomography (CT) because they give advantages in terms of the numerical accuracy and computational complexity. Ramp ...
Lexicon-Free Recognition Strategies For Online Handwritten Tamil Words
(2014-08-07)
In this thesis, we address some of the challenges involved in developing a robust writer-independent, lexicon-free system to recognize online Tamil words. Tamil, being a Dravidian language, is morphologically rich and also ...
Camera-Captured Document Image Analysis
(2014-08-19)
Text is no longer confined to scanned pages and often appears in camera-based images originating from text on real world objects. Unlike the images from conventional flatbed scanners, which have a controlled acquisition ...
Integrated Common And Differential Mode Filters With Active Damping For Active Front End Motor Drives
(2014-07-30)
IGBT based power converters acts as front end in the present day Adjustable Speed Drive (ASD). This offers many advantages and makes regenerative action possible. PWM rectifier operation produces electrically noisy DC bus ...
Geometric And Radiometric Estimation In A Structured-Light 3D Scanner
(2013-10-17)
Measuring 3D surface geometry with precision and accuracy is an important part of many engineering and scientific tasks. 3D Scanning techniques measure surface geometry by estimating the locations of sampled surface points. ...
Performance Evaluation Of Fan-beam And Cone-beam Reconstruction Algorithms With No Backprojection Weight On Truncated Data Problems
(2014-07-16)
This work focuses on using the linear prediction based projection completion for the fan-beam and cone-beam reconstruction algorithm with no backprojection weight. The truncated data problems are addressed in the computed ...
Solar Powered High Voltage Energization For Vehicular Exhaust Cleaning : A Step Towards Possible Retrofitting In Vehicles
(2013-08-28)
In the last few decades India has advanced socioeconomically due to the rapid growth of industries and automobile sector. This in turn increases the use of fossil fuel and diesel. The atmosphere gets polluted due to the ...
Design And Control of Power Converters for Renewable Energy Systems
(2017-09-20)
Renewable energy sources normally require power converters to convert their energy into standardized regulated ac output. The motivation for this thesis is to design and control power converters for renewable energy ...
Spectral And Temporal Zero-Crossings-Based Signal Analysis
(2017-09-20)
We consider real zero-crossing analysis of the real/imaginary parts of the spectrum, namely, spectral zero-crossings (SZCs). The two major contributions are to show that: (i) SZCs provide enable temporal localization of ...
Studies On Epoxy Nanocomposites As Electrical Insulation For High Voltage Power Apparatus
(2016-06-21)
High voltage rotating machines play a significant role in generation and use of electrical energy as the demand for power continues to increase. However, one of the main causes for down times in high voltage rotating ...
