How can image processing
express your imagination?Now that computer graphics has become the tool of choice for illustration, it stands to benefit from an appreciation of the visual form that is not limited to photographic fidelity. Inspired by both art and perception, my work aims to enhance visual communication by extending the range of creative techniques available to artists and designers. At the crossroads of image processing, computer vision and visual art, my research seeks the algorithms to drive novel modes of artistic visual expression.

Automated Non-photorealistic
Progressive Rendering for Image Compression
supervised by Dr.
Neil Dodgson at the Rainbow
Group of the Computer Laboratory,
University of Cambridge (2001)
Abstract: We demonstrate the generation of a wide variety of real-time expressive image rendering styles, ranging from a hand-painted look to an inlay mosaic, by applying geometric subdivision as well as parametric procedural textures to Voronoi spatial partitions. This approach of image reconstruction from scattered color samples provides for an efficient multiresolution image representation. It supports a smooth transition between successive levels of visual abstraction. Its principal application is progressive image compression. By shifting the viewer's expectation from a photograph to a painting, artistic control over the appearance of the compression artifacts may help to improve the perceived visual quality of a highly compressed image.

VoronoImage: A Virtual
Stained Glass Workshop
with for the Computational
Geometry Course at the School
of Computer Science, McGill
University (1998)
Abstract: VoronoImage is a program for the Macintosh which demonstrates an application of computational geometry to rendering a picture into an image resembling a stained glass panel. The technique works through generating a partition tree representing a fractal arrangement of discreet Voronoi diagrams, where each Voronoi polygon is recursively subdivided into a Voronoi diagram. The Voronoi diagrams are calculated using a fast Euclidean distance mapping algorithm.
