Particle Filter Tracking Architecture for use Onboard Unmanned Aerial Vehicles
(Georgia Institute of Technology, 2006-11-14)
Unmanned Aerial Vehicles (UAVs) are capable of placing sensors at unique vantage points without endangering a pilot. Therefore, they are well suited to perform target tracking missions. However, performing the mission ...
Statistical methods for feature extraction in shape analysis and bioinformatics
(Georgia Institute of Technology, 2010-04-05)
The presented research explores two different problems of statistical data analysis.
In the first part of this thesis, a method for 3D shape representation, compression and smoothing is presented. First, a technique for ...
Robust target localization and segmentation using statistical methods
(Georgia Institute of Technology, 2010-04-05)
This thesis aims to contribute to the area of visual tracking, which is the process of identifying an object of interest through a sequence of successive images. The thesis explores kernel-based statistical methods, which ...
Embedded early vision techniques for efficient background modeling and midground detection
(Georgia Institute of Technology, 2010-03-26)
An automated vision system performs critical tasks in video surveillance, while decreasing costs and increasing efficiency. It can provide high quality scene monitoring without the limitations of human distraction and ...
Statistical methods for 2D image segmentation and 3D pose estimation
(Georgia Institute of Technology, 2010-10-26)
The field of computer vision focuses on the goal of developing techniques to exploit and extract information from underlying data that may represent images or other multidimensional data. In particular, two well-studied ...
Illumination compensation in video surveillance analysis
(Georgia Institute of Technology, 2011-03-30)
Problems in automated video surveillance analysis caused by illumination changes are explored, and solutions are presented. Controlled experiments are first conducted to measure the responses of color targets to changes ...
Tracking and detection of cracks using minimal path techniques
(Georgia Institute of Technology, 2010-08-27)
The research in the thesis investigates the use of minimal path techniques to track and
detect cracks, modeled as curves, in critical infrastructure like pavements and bridges. We
developed a novel minimal path algorithm ...
Human computer interface based on hand gesture recognition
(Georgia Institute of Technology, 2010-08-24)
With the improvement of multimedia technologies such as broadband-enabled HDTV, video on demand and internet TV, the computer and the TV are merging to become a single device. Moreover the previously cited technologies as ...
Target tracking using residual vector quantization
(Georgia Institute of Technology, 2011-11-18)
In this work, our goal is to track visual targets using residual vector quantization (RVQ). We compare our results with principal components analysis (PCA) and tree structured vector quantization (TSVQ) based tracking.
This ...
Visual arctic navigation: techniques for autonomous agents in glacial environments
(Georgia Institute of Technology, 2011-06-15)
Arctic regions are thought to be more sensitive to climate change fluctuations, making weather data from these regions more valuable for climate modeling. Scientists have expressed an interest in deploying a robotic sensor ...
