(2020-08-04)Accurate hand segmentation is vital in many applications in which the hands play a central role, such as sign language recognition, action recognition, and gesture recognition. A relatively unexplored obstacle to correct ... -
Hardware And Software Systems For Control Of Assistive Robotic Devices Using Point-of-gaze Estimation
Eye gaze based interaction has many useful applications in human-machine interfaces, assistive technologies, and multimodal systems. Traditional input methods, such as the keyboard and mouse, are not practical in many ... -
Helmholtz's Theorem Based Parametric Non-rigid Image Registration
(Computer Science & Engineering, 2009-09-16)Helmholtz's theorem states that, with suitable boundary condition, a vector field is completely determined if both of its divergence and curl are specified everywhere. Based on this, we developed a new parametric non-rigid ... -
Hierarchical Representation Learning with Connectionist Models
(2018-03-01)To unleash the power of big data, efficient algorithms which are scalable to millions of data are desired. Deep learning is one area that benefits from big data enormously. Deep learning uses neural networks to mimic human ... -
High Performance Real-time Embedded Systems: Design And Implementation Of Road Surface Analyzer System
(Computer Science & Engineering, 2010-07-19)Multi-core processors are becoming main components for many embedded systems. Designing such embedded systems is a complex task, since developers must deal with a number of issues such as multi-threading and optimal use ... -
A Holistic, Similarity-based Approach For Personalized Ranking In Web Databases
(Computer Science & Engineering, 2011-10-11)With the advent of the Web, the notion of ``information retrieval'' has acquired a completely new connotation and currently encompasses several disciplines ranging from traditional forms of text and data retrieval in ... -
Human Behavior Modeling in Long Videos: Drowsiness Detection and Action Segmentation
(2022-05-09)"In this thesis we focus on two instances of human behavior modeling in long untrimmed videos: drowsiness detection, and action segmentation. In the first section, we focus on drowsiness detection. Specifically, we introduce ... -
HUMAN FACTORS ANALYSIS AND MONITORING TO ENHANCE HUMAN-ROBOT COLLABORATION
(2021-05-11)Human-Machine Interaction (HMI) can be defined as a way for us to communicate with machines through user interfaces. User interfaces have evolved from complicated punch cards and levers in the first analog computers to a ... -
Human Factors In Textual Password-based Authentication
Despite being the most commonly used method of authentication on the Web, textual password-based authentication is by no means a panacea as long as usability is concerned. In this dissertation work, we address some usability ... -
Hyper-optimized Machine Learning and Deep Learning Methods For Geo-spatial and Temporal Function Estimation
(2018-08-13)Owing to a high degree of freedom in human mobility, accurate modelling/estimation of human mobility function remains a challenge. Numerous work in the literature have tried to address the challenge using various traditional ... -
Image Annotation And Feature Engineering Via Structural Sparsity And Low Rank Approximation
(Computer Science & Engineering, 2014-03-12)Nowadays, in order to sense environment and understand human behaviors, data analysis plays a more and more important role to handle heterogeneous data ranging from different domains, e.g., image categorization/annotation, ... -
Improving Accuracy in Large Vocabulary Sign Search Systems
(2016-08-26)An automated computer vision-based dictionary system for looking up the meaning of signs can be an invaluable tool both for students and native users of sign languages. Students may not know the meaning of a sign they ... -
Improving Performance and Security in Anonymity Systems
(2018-09-06)Tor is an anonymity network that provides online privacy for the Internet users. Tor hides the user's traffic among the others' traffic. The more users Tor attracts, the stronger anonymity it provides. Unfortunately, users ... -
Improving Privacy And Performance In Anonymous Communications
(Computer Science & Engineering, 2011-03-03)Anonymous communications systems provide an important privacy service by keeping passive eavesdroppers from linking communicating parties. However, an attacker can use long-term statistical analysis of traffic sent to and ... -
