We present a vision system for the 3-D model-based t r acking of unconstrained human movement. Using image sequences acquired simultaneously f r om multiple views, we recover the 3-D body pose at each time instant without the use of markers. The pose-recovery problem is formulated a s a s e arch problem and entails nding the pose parameters of a graphical human model whose synthesized a p p ear...

In order to analyze the behavior of moving objects, a measure for determining the similarity of trajectories needs to be defined. Although research has been conducted that retrieved similar trajectories of moving objects in Euclidean space, very little research has been conducted on moving objects in the space defined by road networks. In terms of real applications, most moving objects are loca...

The relevant HIV data sets used for predicting outcomes of HIV combination therapies suffer from several problems: different treatment backgrounds of the samples, uneven representation with respect to the level of therapy experience and uneven therapy representation. Also, they comprise only viral strain(s) that can be detected in the patients’ blood serum. The approach presented in this paper ...

In this paper, we introduce a projection technique that aims to place points representing individual images in a two-dimensional visualization space so that proximity in this space reflects some sort of similarity between the images. This visualization technique enables users to employ their visual ability to evaluate the significance of metadata as well as the characteristics of classification...

A nonparametric clustering technique incorporating the concept of similarity based on the sharing of near neighbors is presented. In addition to being an essentially paraliel approach, the computational elegance of the method is such that the scheme is applicable to a wide class of practical problems involving large sample size and high dimensionality. No attempt is made to show how a priori pr...

In this paper we describe an application of language technology to policy formulation, where it can support policy makers assess the acceptance of a yet-unpublished policy before the policy enters public consultation. One of the key concepts is that instead of relying on thematic similarity, we extract arguments expressed in support or opposition of positions that are general statements that ar...

We introduce the concept of generalised interval-valued fuzzy soft set and its operations and study some of their properties. We give applications of this theory in solving a decision making problem. We also introduce a similarity measure of two generalised interval-valued fuzzy soft sets and discuss its application in amedical diagnosis problem: fuzzy set; soft set; fuzzy soft set; generalised...

Previous work has explored the concept of music similarity measures and a variety of methods have been proposed for calculating such measures. This paper describes a system for music similarity which attempts to model and compare some of the more musically salient features of a set of audio signals. A model for timbre and a model for rhythm are implemented directly from previous work, and a mod...

Based on the axiom de nition of distance measure, some new formulas of fuzzy entropy induced by distance measure and some new properties of distance measure are given. A characterization of a -distance measure is a metric de ned on all fuzzy sets is obtained. c © 2001 Elsevier Science B.V. All rights reserved.

In this work we look into the details of modeling shapes in an ontology as property restrictions on classes. In this way shapes do not have to be categorized in an exhaustive hierarchy and there is no need to take immediate decisions on how to group the objects, it is rather possible to individualize some important characteristics of shapes and use them as the basis for their categorization and...
