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 ...
DeNOx Studies In Diesel Exhaust Under AC/Pulse Energizations
(2015-11-16)
It is the need of the hour to reduce the pollutants which poison our atmosphere and harm our health. The diesel engines are the most efficient IC engines in the world today, but paradoxically, they are also the engines ...
Dead-Time Induced Oscillations in Voltage Source Inverter-Fed Induction Motor Drives
(2017-12-07)
The inverter dead-time is integral to the safety of a voltage source inverter (VSI). Dead-time is introduced between the complementary gating signals of the top and bottom switches in each VSI leg to prevent shoot-through ...
Sparsity Motivated Auditory Wavelet Representation and Blind Deconvolution
(2018-08-29)
In many scenarios, events such as singularities and transients that carry important information about a signal undergo spreading during acquisition or transmission and it is important to localize the events. For example, ...
Trajectory-based Descriptors for Action Recognition in Real-world Videos
(2018-07-30)
This thesis explores motion trajectory-based approaches to recognize human actions in
real-world, unconstrained videos. Recognizing actions is an important task in applications
such as video retrieval, surveillance, ...
