The roles of object-image relative motion and static depth information in the perception of heading

Investigates visual information that enables human to effectively guide their movement through the environment. This problem is fundamental to the study of human behaviour, since survival is contingent upon the acquisition of resources that lie in different locations throughout the environment.

Novel spectral descriptor for object shape

In this paper, we propose a novel descriptor for shapes. The proposed descriptor is obtained from 3D spherical harmonics. The inadequacy of 2D spherical harmonics is addressed and the method to obtain 3D spherical harmonics is described. 3D spherical harmonics requires construction of a 3D model which implicitly represents rich features of objects. Spherical harmonics are used to obtain descriptors from the 3D models. The performance of the proposed method is compared against the CSS approach which is the MPEG-7 descriptor for shape contour. MPEG-7 dataset of shape contours, namely, CE-1 is used to perform the experiments. It is shown that the proposed method is effective.

Critique and creativity : the pedagogical nexus between literary studies and creative writing

This paper will explore the nexus between literary studies and creative writing on the basis of Stanley Aronowitz’s and Henry Giroux’s work on the democratic potential embedded in a critical literacy education, which provides ‘a language of critique’ and ‘a language of possibility’ (1993: 46). This paper argues that literary studies and
creative writing, as cognate disciplines focused precisely on languages of critique and possibility, are uniquely positioned to cooperatively enact this pedagogical agenda.

Scandalous texts : the anxieties of the literary

This thesis explores contemporary literary scandals in order to identify the cultural and literary anxieties revealed by controversial works. Examining how scandals emerge in relation to challenging representations of children, women, religion and authenticity, the thesis argues that literary controversies reveal concerns about the construction of identity, history and reality.

A generic virtual reality interaction system and its extensions using the common object request broker architecture (CORBA)

The paper describes the design and implementation of an immersive Virtual Reality (VR) interaction system. The system aims to provide a flexible mechanism for programmers to implement interaction in their VR applications, making good use of all accepted practices in the field. The paper further describes how the system was extended to a multi-user system using the CORBA middleware layer.

Procedural modeling facilities for hierarchical object generation

We modify a selection of interactive modeling tools for use in a procedural modeling environment. These tools are selection, extrusion, subdivision and curve shaping. We create human models to demonstrate that these tools are appropriate for use on hierarchical objects. Our tools support the main benefits of procedural modeling, which are: the use of parameterisation to control and very a model, varying levels of detail, increased model complexity, base shape independence and database amplification. We demonstrate scripts which provide each of these benefits.
