Looking beneath the surface.

Beneath the Paint: A Visual Journey through Conceptual Metaphor Violation

Metaphors are an undeniable part of many forms of art and they hint at the underlying conceptualisation that takes place in the silent conversation between an art piece and its perceiver. Abstract art, in particular, requires the viewer not only to analyse the colour palette and the shapes of the strokes but to subconsciously react to the underlying structures that often define the metaphors. A...

An Interactive Non-Photorealistic Canvas

Within the area of non-photorealistic rendering, many techniques have been developed to simulate a wide variety of different styles. However, these styles are usually globally applied to some form of model that is provided as input and specific local interaction is often not possible. This thesis explores the application of the paradigm of modeling with rendering primitives to enable users to f...

Morphons: Paint on Priors and Elastic Canvas for Segmentation and Registration

This paper presents a new robust approach for registration and segmentation. Segmentation as well as registration is attained by morphing of an N -dimensional model, the Morphon, onto the N dimensional data. The approach is general and can, in fact, be said to encompass much of the deformable model ideas that have evolved over the years. However, in contrast to commonly used models, a distingui...

Dynamic Canvas for Non-Photorealistic Walkthroughs

The static background paper or canvas texture usually used for non-photorealistic animation greatly impedes the sensation of motion and results in a disturbing “shower door” effect. We present a method to animate the background canvas for non-photorealistic rendering animations and walkthroughs, which greatly improves the sensation of motion and 3D “immersion”. The complex motion field induced ...
