PhD Thesis Proposal

Event Location: NSH 1305Abstract: Snake robots are ideally suited to highly confined environments because their small cross-sections and highly redundant kinematics allow them to enter and move through tight spaces with a high degree of dexterity. Despite these theoretical advantages, snake robots also pose a number of practical challenges that have limited their usefulness in [...]

Event Location: NSH 1507Abstract: Many computer vision problems, such as object classification, motion estimation or shape registration rely on solving the correspondence problem. Existing algorithms to solve the correspondence problems are usually NP-hard, difficult to approximate and lack mechanism for feature selection. This proposal addresses the correspondence problem in computer vision, and proposes two new [...]

Event Location: NSH 3305Abstract: A new trainable model and method for generating prosody for speech synthesis is proposed, in which a relationship between pragmatics, intonational phonology, and performance is made explicit in a language-neutral manner. The literature of pragmatics and intonation is broad, but produces only coarse descriptions and few actionable models (Steedman; Pierrehumbert and [...]

Event Location: NSH 1305Abstract: This thesis provides a system that allows users to interact with objects and human subjects in photographs in three dimensions. Current photo-editing tools provide a diverse array of operations in photographs. However, they are limited to the 2D plane of the image. The key contribution of this thesis is to leverage [...]

Event Location: GHC 8102Abstract: This research addresses the problem of planning views for modeling large, local, substantially 3D terrain features, such as skylights, at long range from surface rovers. Skylights, which are vertical cave entrances, and other pits have been identified in recent high-resolution images of the Moon and Mars. Planetary pits are interesting scientific [...]

Event Location: NSH 1507Abstract: In the United States the annual cost of cardiovascular disease exceeds $475 billion. Medical imaging costs more than $100 billion annually, with cardiovascular imaging representing almost one-third. Any approach that can reduce the need for imaging in cardiovascular care has the potential to provide significant savings. Without direct visualization of the [...]

Event Location: NSH 1305Abstract: Motion planning is a central problem in robotics and is crucial to finding paths to navigate and manipulate safely and efficiently. Ideally, we want planners which find paths quickly and of good quality. Additionally, planners should generate predictable motions, which are safer when operating in the presence of humans. While the [...]

Event Location: NSH 1305Abstract: Planning optimal paths for large numbers of robots is computationally expensive.  In our research, we developed a new framework for multirobot path planning called subdimensional expansion, which initially plans for each robot individually, and then coordinates motion among the robots as needed.  More specifically, subdimensional expansion initially creates a one-dimensional search [...]

Event Location: NSH 1305Abstract: Increasingly, real world problems require multiple predictions. For instance in advertisement placement on the web, a list of advertisements is placed on a page with the objective of maximizing click- through rate. Traditionally machine learning has focused on producing a single best prediction. More generally, in this thesis, we build an [...]

Event Location: GHC 8102Abstract: Fast and accurate human pose estimation enables a wide spectrum of applications from interactive control, markerless motion capture and gesture recognition to providing rich semantic information for higher level vision tasks such as scene understanding. The goal of this work is to develop an accurate and real-time human pose estimation system [...]
