Dr. Tim Bruylants

Biography

Tim Bruylants graduated as Master of Science in 2001 at the University of Antwerp. He started out, working for asmall private company as a systems designer and programmer, creating document publishing software. In 2005, he participated as a member of the Forms Working Group (W3C). At the end of 2006, Tim Bruylants became a PhD student at the Vrije Universiteit Brussel. The main topic of his research is the compression of volumetric data sets, using wavelet and geometric transforms. Since 2005, Tim Bruylants is also an active member of the JPEG committee. He is co-editor of the JPEG 2000 Part 10 (JP3D) specification.

Research Interest

His research focuses on improving the compression efficiency for digital images, specifically targeting volumetric biomedical imagery. After investigating new techniques and methodologies that improve on the complexity and quality performance of wavelet-based image coding, he currently explores the deployment of efficient geometric representations, such as contourlets, to higher-dimensional information. Recent international research on these geometric representations spent insufficient attention to practical compression algorithms. As such, his research tries to improve on this aspect by digging deeper into the domain of wavelets and their derived geometric transforms. In (bio-) medical imaging, techniques such as computed tomography (CT), magnetic resonance imaging (MRI) or the recent multimodal microscopy modalities are major producers of medical image data. With the on-going advances in scanner technology, the amounts and sizes of the produced data are continuously increasing. Tim Bruylants contributes solutions to this challenging domain by providing an efficient representation technology that allows for compact and efficient storage and visualization solutions. Tim Bruylants works on designing an algorithm for efficiently compressing volumetric images by use of wavelet transforms. One part of his research already resulted in the JP3D extension of the international JPEG 2000 standard, enabling it to compress volumetric images. He currently continues his research to improve even further the state-of-the-art compression efficiency.
