Color Separation For Image Segmentation, Meng Tang
Color Separation For Image Segmentation, Meng Tang
Electronic Thesis and Dissertation Repository
Image segmentation is a fundamental problem in computer vision that has drawn intensive research attention during the past few decades, resulting in a variety of segmentation algorithms. Segmentation is often formulated as a Markov random field (MRF) and the solution corresponding to the maximum a posteriori probability (MAP) is found using energy minimiza- tion framework. Many standard segmentation techniques rely on foreground and background appearance models given a priori. In this case the corresponding energy can be efficiently op- timized globally. If the appearance models are not known, the energy becomes NP-hard, and many methods resort to iterative schemes that …
Detecting Multilingual Lines Of Text With Fusion Moves, Igor Milevskiy
Detecting Multilingual Lines Of Text With Fusion Moves, Igor Milevskiy
Electronic Thesis and Dissertation Repository
This thesis proposes an optimization-based algorithm for detecting lines of text in images taken by hand-held cameras. The majority of existing methods for this problem assume alphabet-based texts (e.g. in Latin or Greek) and they use heuristics specific to such texts: proximity between letters within one line, larger distance between separate lines, etc. We are interested in a more challenging problem where images combine alphabet and logographic characters from multiple languages where typographic rules vary a lot (e.g. English, Korean, and Chinese). Significantly higher complexity of fitting multiple lines of text in different languages calls for an energy-based formulation combining …
Reinforcement Learning With Motivations For Realistic Agents, Jacquelyne T. Forgette
Reinforcement Learning With Motivations For Realistic Agents, Jacquelyne T. Forgette
Electronic Thesis and Dissertation Repository
Believable virtual humans have important applications in various fields, including computer based video games. The challenge in programming video games is to produce a non-player controlled character that is autonomous, and capable of action selections that appear human. In this thesis, motivations are used as a basis for learning using reinforcements. With motives driving the decisions of the agents, their actions will appear less structured and repetitious, and more human in nature. This will also allow developers to easily create game agents with specific motivations, based mostly on their narrative purposes. With minimum and maximum desirable motive values, the agents …
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 …
Hierarchical Classification And Its Application In University Search, Xiao Li
Hierarchical Classification And Its Application In University Search, Xiao Li
Electronic Thesis and Dissertation Repository
Web search engines have been adopted by most universities for searching webpages in their own domains. Basically, a user sends keywords to the search engine and the search engine returns a flat ranked list of webpages. However, in university search, user queries are usually related to topics. Simple keyword queries are often insufficient to express topics as keywords. On the other hand, most E-commerce sites allow users to browse and search products in various hierarchies. It would be ideal if hierarchical browsing and keyword search can be seamlessly combined for university search engines. The main difficulty is to automatically classify …
An Architecture For Believable Socially Aware Agents, Arvand Dorgoly
An Architecture For Believable Socially Aware Agents, Arvand Dorgoly
Electronic Thesis and Dissertation Repository
The main focus of this thesis is to solve the believability problem in video game agents by integrating necessary psychological and sociological foundations by means of role based architecture. Our design agent also has the capability to reason and predict the decisions of other actors by using its own mental model. The agent has a separate mental model for every actor.
