(2009-07-24)
In the fast growing field of Telecommunications, the back up DC power supply plays a vital role in powering the telecom equipment. This DC power supply is a combination of AC-DC Rectifier coupled with a battery bank to ...
Signal Processing Algorithms For Digital Image Forensics
(2010-03-19)
Availability of digital cameras in various forms and user-friendly image editing softwares has enabled people to create and manipulate digital images easily. While image editing can be used for enhancing the quality of the ...
Coupling Of Electromagnetic Fields From Intentional High Power Electromagnetic Sources With A Buried Cable And An Airborne Vehicle In Flight
(2017-05-23)
Society’s dependence on electronic and electrical systems has increased rapidly over the past few decades, and people are relying more and more on these gadgets in their daily life because of the efficiency in operation ...
Methods for Text Segmentation from Scene Images
(2017-09-27)
Recognition of text from camera-captured scene/born-digital images help in the development of aids for the blind, unmanned navigation systems and spam filters. However, text in such images is not confined to any page layout, ...
DSA Image Registration And Respiratory Motion Tracking Using Probabilistic Graphical Models
(2017-10-18)
This thesis addresses three problems related to image registration, prediction and tracking, applied to Angiography and Oncology. For image analysis, various probabilistic models have been employed to characterize the image ...
On Maximizing The Performance Of The Bilateral Filter For Image Denoising
(2017-07-07)
We address the problem of image denoising for additive white Gaussian noise (AWGN), Poisson noise, and Chi-squared noise scenarios. Thermal noise in electronic circuitry in camera hardware can be modeled as AWGN. Poisson ...
Study On DC-Link Capacitor Current In A Three-Level Neutral-Point Clamped Inverter
(2017-05-24)
Three-level diode-clamped inverter is being widely used these days. Extensive research has been carried out on pulse width modulation (PWM) strategies for a three-level inverter. The most widely used PWM strategies are ...
Multiview Face Detection And Free Form Face Recognition For Surveillance
(2014-10-15)
The problem of face detection and recognition within a given database has become one of the important problems in computer vision. A simple approach for Face Detection in video is to run a learning based face detector every ...
Motion Estimation From Moments Of Projection Data For Dynamic CT
(2016-09-15)
In X-ray computed tomography, motion of the object (breathing, for example)
while X-ray projections are acquired for tomographic reconstruction leads to mo-
tion artifacts in the reconstructed image. Object motion (such ...
Dimensioning Of Corona Control Rings For EHV/UHV Line Hardware And Substations
(2015-07-13)
High voltage (EHV and UHV) transmission facilitates transfer of large amount of power over long distances. However, due to the inherent geometry, the line and substation hardware of EHV and UHV class generate high electric ...
