The study of sign languages provides a wide field of applications for computer vision systems, but the analysis of such gestures often leads to complex 3D reconstructions or to ambiguities. In this paper, we describe the architecture of an image analysis system that performs sign language analysis by using a prediction/verification approach. The system integrates a model of the sign language’s ...

In the design of recent systems, I have advanced techniques that position graphic synthesis methods in the context of solo, improvisational performance. Here, the primary interfaces for musical action are prepared works on paper, scanned by digital video cameras which in turn pass image data on to software for analysis and interpretation as sound synthesis and signal processing procedures. The ...

Supervisory Committee Bruce Gooch, Supervisor Department of Computer Science Amy Gooch, Departmental Member Department of Computer Science Brian Wyvill, Departmental Member Department of Computer Science Wu-Sheng Lu, Outside Member Department of Electrical and Computer Engineering I present an unsupervised system that takes digital photographs as input, and generates simplified, stylized vector...

When humans sense the weight of real objects, their perception is known to be influenced by not only tactile information but also visual information. In a Mixed-Reality (MR) environment, the appearance of touchable objects can be changed by superimposing a computer-generated image (CGI) onto them (MR visual stimulation). In this paper, we studied the psychophysical influence on the sense of wei...

In this paper, we propose a novel temporal template, called Chrono-Gait Image (CGI), to describe the spatio-temporal walking pattern for human identification by gait. The CGI temporal template encodes the temporal information among gait frames via color mapping to improve the recognition performance. Our method starts with the extraction of the contour in each gait image, followed by utilizing ...

This paper presents a novel hybrid rendering system, which allows users to interact with 3D graphic objects in an image-based environment. To represent a complex environment, we use a collection of images captured by a longitudinally aligned camera array, which rotates along a circle. The captured images are indexed and compressed for efficient rendering of the environment. Moreover, users can ...

BACKGROUND In 2006, Australia introduced graphic cigarette packet warnings. The new warnings include one of 14 pictures, many depicting tobacco-related pathology. The warnings were introduced in two sets; Set A in March and Set B from November. This study explores their impact on smokers' beliefs about smoking related illnesses. This study also examines the varying impact of different warnings,...
