Reconstructing Point Clouds Of Mid-Size Objects, Spencer Woodworth
Reconstructing Point Clouds Of Mid-Size Objects, Spencer Woodworth
Computer Science and Software Engineering
This project explores the use of an inexpensive 3D camera for the acquisition and reconstruction of mid-size objects. The disparity of objects between stereo image pairs are used to calculate depth and generate a depth map. The depth map is used to generate a point cloud representation of the object from a single view. Finally, point clouds are generated from several views of an object and then aligned and merged into a seamless 360-degree point cloud.
A Bandwidth-Conserving Architecture For Crawling Virtual Worlds, Dipesh Gautam
A Bandwidth-Conserving Architecture For Crawling Virtual Worlds, Dipesh Gautam
Graduate Theses and Dissertations
A virtual world is a computer-based simulated environment intended for its users to inhabit via avatars. Content in virtual worlds such as Second Life or OpenSimulator is increasingly presented using three-dimensional (3D) dynamic presentation technologies that challenge traditional search technologies. As 3D environments become both more prevalent and more fragmented, the need for a data crawler and distributed search service will continue to grow. By increasing the visibility of content across virtual world servers in order to better collect and integrate the 3D data we can also improve the crawling and searching efficiency and accuracy by avoiding crawling unchanged regions …
Representation, Recognition And Collaboration With Digital Ink, Rui Hu
Representation, Recognition And Collaboration With Digital Ink, Rui Hu
Electronic Thesis and Dissertation Repository
Pen input for computing devices is now widespread, providing a promising interaction mechanism for many purposes. Nevertheless, the diverse nature of digital ink and varied application domains still present many challenges. First, the sampling rate and resolution of pen-based devices keep improving, making input data more costly to process and store. At the same time, existing applications typically record digital ink either in proprietary formats, which are restricted to single platforms and consequently lack portability, or simply as images, which lose important information. Moreover, in certain domains such as mathematics, current systems are now achieving good recognition rates on individual …
Vehicular Instrumentation And Data Processing For The Study Of Driver Intent, Taha Kowsari
Vehicular Instrumentation And Data Processing For The Study Of Driver Intent, Taha Kowsari
Electronic Thesis and Dissertation Repository
The primary goal of this thesis is to provide processed experimental data needed to determine whether driver intentionality and driving-related actions can be predicted from quantitative and qualitative analysis of driver behaviour. Towards this end, an instrumented experimental vehicle capable of recording several synchronized streams of data from the surroundings of the vehicle, the driver gaze with head pose and the vehicle state in a naturalistic driving environment was designed and developed. Several driving data sequences in both urban and rural environments were recorded with the instrumented vehicle. These sequences were automatically annotated for relevant artifacts such as lanes, vehicles …
Channels: Easy Video Content Consumption, Alexander R. Ledwith
Channels: Easy Video Content Consumption, Alexander R. Ledwith
Computer Engineering
The idea for this project is to take a user’s digital movie and television show library, and organize the individual videos into lists that will continuously and concurrently play like cable TV channels. This means that when a list of channels is switched to, video content will automatically start playing, possibly in the middle, based on a schedule. It should serve the needs of the user by allowing the user to quickly watch any of their existing channels, easily add a new channel based on chosen criteria or manual selection, and easily add new video content. In addition, the product …
Misheard Me Oronyminator: Using Oronyms To Validate The Correctness Of Frequency Dictionaries, Jennifer G. Hughes
Misheard Me Oronyminator: Using Oronyms To Validate The Correctness Of Frequency Dictionaries, Jennifer G. Hughes
Master's Theses
In the field of speech recognition, an algorithm must learn to tell the difference between "a nice rock" and "a gneiss rock". These identical-sounding phrases are called oronyms. Word frequency dictionaries are often used by speech recognition systems to help resolve phonetic sequences with more than one possible orthographic phrase interpretation, by looking up which oronym of the root phonetic sequence contains the most-common words.
Our paper demonstrates a technique used to validate word frequency dictionary values. We chose to use frequency values from the UNISYN dictionary, which tallies each word on a per-occurance basis, using a proprietary text corpus, …
Project Writeup On Amethyst: A 3d Adventure Game For Tablets, Adam Hintz
Project Writeup On Amethyst: A 3d Adventure Game For Tablets, Adam Hintz
Computer Science and Software Engineering
Amethyst is a point-and-click science fiction adventure game for tablets, developed over two quarters to demonstrate applied principles of computer graphics and software engineering discipline. Using a novel interaction system, players can engage in environmental puzzles. Development of Amethyst required non-trivial quality assurance measures and workflow enhancements. The end result is a functional technical demo showcasing a single level, with the ability to rapidly produce more content.
