Adaptive medial-axis approximation for sphere-tree construction
(2004)Hierarchical object representations play an important role in performing efficient collision handling. Many different geometric primitives have been used to construct these representations, which allow areas of interaction ... -
ALOHA: Adaptive Level of Detail for Human Animation: Towards and new Framework.
(2000)The task of animating and rendering virtual humans in real-time is challenging. One must first establish a sense of realism through appearance, and then maintain this realism through correct and plausible motion, while ... -
An Analysis of Case-Base Editing in a Spam Filtering System
(Trinity College Dublin, Department of Computer Science, 2004-08)Because of the volume of spam email and its evolving nature, any deployed Machine Learning-based spam filtering system will need to have procedures for case-base maintenance. Key to this will be procedures to edit ... -
Analysis of visibility masks and resultant image quality
(2000)Virtual Interfaces and Visibility Masks are an extremely efficient method for parallelising the Radiosity Method. They exploit data locality, and keep communication between nodes as low as possible. Previous papers on ... -
Animating humans on handlheld devices for interactive gaming
(2005)This paper examines the implementation and efficacy of impostor-based techniques on smallscreen devices, and compares their effectiveness with that of the same techniques when used on desktop computers. Firstly, a ... -
Automatic Segmentation and Inpainting of Specular Highlights for Endoscopic Imaging
(2010)Minimally invasive medical procedures have become increasingly common in today's healthcare practice. Images taken during such procedures largely show tissues of human organs, such as the mucosa of the gastrointestinal ... -
Blame-Based Noise Reduction: An Alternative Perspective on Noise Reduction for Lazy Learning
(Trinity College Dublin, Department of Computer Science, 2005-02-22)In this paper we present a new perspective on noise reduction for nearest-neighbour classifiers. Classic noise reduction algorithms such as Repeated Edited Nearest Neighbour remove cases from the training set if they are ... -
A Comparison of Ensemble and Case-Base Maintenance Techniques for Handling Concept Drift in Spam Filtering
(Trinity College Dublin, Department of Computer Science, 2005)The problem of concept drift has recently received considerable attention in machine learning research. One important practical problem where concept drift needs to be addressed is spam filtering. The literature on ... -
Crowd and group simulation with levels of detail for geometry, motion and conversational behaviour
(2002)Work on levels of detail for human simulation has occurred mainly on a geometrical level, either by reducing the numbers of polygons representing a virtual human, or replacing them with a two-dimensional imposter. ... -
Digital Game-based Learning for Early Childhood
(Learnovate Centre, 2013)This report presents a comprehensive review of the research evidence for the effectiveness of digital game-based learning for early childhood learning. The report also identifies the types of learning content suited to a ... -
Exploiting Re-ranking Information in a Case-Based Personal
(Trinity College Dublin, Department of Computer Science, 2003)Intelligent software assistants are becoming more common in the e-commerce domain. We are working on a personal travel assistant. The goal of this application is to use case based reasoning to assist the user in arranging ... -
Extracting geometric models from medieval moundling profiles for case-based reasoning
(2000)Cross-sectional profiles of medieval mouldings are often considered to be a vital form of data for art historians. Mouldings have often been used to highlight salient areas of buildings, and they provide a wealth of ... -
Eye-tracking for efficient database labelling: Applications to automatic analysis of colonoscopy video
(2007)In this paper we present our preliminary results in the automatic analysis of colonoscopy video using eye-tracking. We propose that eye-tracking can be successfully applied to solve different problems in computer assisted ... -
A General-Purpose Taxonomy of Computer-Augmented Sports Systems
(IGI Global, 2009)The area of computer-augmented sports is large and complex and spans several disciplines. This chapter presents a general-purpose taxonomy of computer-augmented sports systems, which is intended to assist researchers and ... -
Geometry reduction for urban simulation on handheld devices
(2005)We present a real-time urban simulation on a Personal Digital Assistant (PDA). An existing desktop urban simulation is used to automatically generate potential visibility data, sub-divide the world into areas of similar ... -
Improving Recommendation Ranking by Learning Personal Feature Weights
(Trinity College Dublin, Department of Computer Science, 2004-06-24)The ranking of offers is an issue in e-commerce that has received a lot of attention in Case-Based Reasoning research. In the absence of a sales assistant, it is important to provide a facility that will bring suitable ... -
An Indoor Resource Optimisation using Ray-Tracing Techniques and Signal-To-Interference Object Function to Obtain Best Capacity
(2014)The purpose of this work is to produce a method that calculates the best locations of a multiple transmitters in an indoor environment whilst meeting the required user capacity. The method uses a non-standard building ... -
Levels of detail for crowds and groups
(Blackwell, 2002)Work on levels of detail for human simulation has occurred mainly on a geometrical level, either by reducing the numbers of polygons representing a virtual human, or replacing them with a two-dimensional imposter. ...
