“In the world of ICT there are the many and then there are the few... who have the depth to understand the science of how those waveforms actually work and the practical burdens of making them work within complex networks. It is also the few who can apply that knowledge for the moment when it's about the science of making a successful business. Wim is all of these and more. His ability to see beyond the moment over the horizon of what has not been done before and the manner of how he engages with all manner of people with all the varied skills to be successful in the business of ICT is what sets him apart as a true talent, a wonderful person to work with and the person I would seek first in any business venture - even to have a moment of leisure with a beer.”

Nonlinear Wavelet Transforms for Image Coding via Lifting
IEEE Transactions on Image Processing, Vol. 12 No. 12, 1449-1459
We examine the central issues of invertibility, stability, artifacts, and frequency-domain characteristics in the construction of non-linear analogs of the wavelet transform. The lifting framework for wavelet construction motivates our analysis and provides new insight into the problem. We describe a new type of non-linearity for use in constructing non-linear transforms: a set of linear predictors that are chosen adaptively using a non-linear selection function. We also describe how a…
We examine the central issues of invertibility, stability, artifacts, and frequency-domain characteristics in the construction of non-linear analogs of the wavelet transform. The lifting framework for wavelet construction motivates our analysis and provides new insight into the problem. We describe a new type of non-linearity for use in constructing non-linear transforms: a set of linear predictors that are chosen adaptively using a non-linear selection function. We also describe how a previously studied family of non-linear filter banks can be extended through the use of prediction functions operating on a causal neighborhood. We present preliminary results for a synthetic test image.

Non-uniform relaxation procedure for multiresolution mesh processing
Issued USPTO 08830235
An irregular connectivity mesh representative of a surface having an arbitrary topology is processed using a non-uniform relaxation procedure. The non-uniform relaxation procedure minimizes differences between vectors normal to faces of pairs of triangles having a common edge and located within a designated neighborhood of a given vertex. The relaxation procedure may be used to construct subdivision and pyramid algorithms for performing processing operations such as upsampling, downsampling and…
An irregular connectivity mesh representative of a surface having an arbitrary topology is processed using a non-uniform relaxation procedure. The non-uniform relaxation procedure minimizes differences between vectors normal to faces of pairs of triangles having a common edge and located within a designated neighborhood of a given vertex. The relaxation procedure may be used to construct subdivision and pyramid algorithms for performing processing operations such as upsampling, downsampling and filtering on irregular connectivity meshes. The signal processing algorithms may be utilized in applications such as smoothing, enhancement, editing, texture mapping and compression.
