Culberson, Joseph, Evans, Patricia

Technical report TR94-09. In this paper we explore the relationship between asymmetries in deletion algorithms used in updating binary search trees, and the resulting long term behavior of the search trees. We show that even what would appear to be negligible asymmetric effects accumulate to...

Technical report TR06-09. This paper presents a new technique, called aura 3D textures, for generating solid textures based on input examples. Our method is fully automatic and requires no user interactions in the process. Given an input texture sample, our method first creates its aura matrix...

Qin, Xuejie, Yang, Herb

Technical report TR05-30. This paper presents a new technique, called aura texture, for generating synthetic textures from input examples. The basic idea of the new approach is to model textures using Asymmetric Gray Level Aura Matrices (AGLAMs), which give (the proof is in a recently submitted...

Yuan, Li-Yan, You, Jia-Huai

Technical report TR92-18. We propose a framework of autoepistemic reasoning in which the underlying semantics is determined by the choice of a nonmonotonic inference mechanism and by specifying a belief constraint. While the latter makes the approach flexible in meeting possibly different...

Yuan, Li-Yan

Technical report TR93-17. We study the expressive power of first order autoepistemic logic. We argue that full introspection of rational agents should be carried out by minimizing positive introspection and maximizing negative introspection. Based on full introspection, we propose the...

Schmidt, Mark

Technical report TR05-13. This thesis addresses the task of automatic segmentation of brain tumors and edema in Magnetic Resonance images. This is motivated by potential applications in assessing tumor growth, assessing treatment responses, computer-assisted surgery, radiation therapy target...

Wang, Tao

Technical report TR09-11. An automatic brain tumor segmentation method is presented in this paper. This method has 3 stages. In the first stage, a so-called Normalized Gaussian Mixture Model (NGMM) is proposed and used to model the brain tissues. In the second stage, a Gaussian Bayesian...

Wang, Tao, Basu, Anup

Technical report TR05-32. An algorithm for automatic estimation of 3D transformations between two objects is presented in this paper. Skeletons of the 3D objects are created with a fully parallel thinning algorithm and feature point pairs (land markers) are extracted from skeletons automatically,...

Ghose, Aditya, Geobel, Randy, Yuan, Li-Yan

Technical report TR92-09. In many database applications, designers can easily provide at least some information about the relative importance of the information to be stored and manipulated. While of potentially high value, the ordering information is typically only partial. Here we address the...

1996

Elio, Renee, Pelletier, Francis Jeffry

Technical report TR96-01. Five experiments investigated human belief revision, defining belief revision as a required change to an initial set of beliefs, modeled as a set of propositional sentences, when new information presents a logical inconsistency with the initial set. Certain prescriptive...
