Bio-sketch:<br />
Pr<strong>of</strong>essor Lucier has worked for over ten years on wavelet and multiresolution methods for image processing and other<br />
applications. He has a particular interest in applications in medical imaging (image compression for telemedicine,<br />
tomographic and MRI reconstruction, etc.).<br />
The selected publications below indicate some <strong>of</strong> these interests. The first paper relates variational problems to wavelet<br />
shrinkage, as introduced by David Donoho and Iain Johnstone. The second paper gives an interpretation <strong>of</strong> translation-invariant<br />
wavelet shrinkage, introduced by Donoho and Ronald Coifman, as gradient descent along a convex functional;<br />
Gaussian smoothing can be interpreted in the same way (with a different functional).<br />
Finally, the third paper introduces several results about wavelet methods for medical tomography, especially for<br />
Positron Emission Tomography (PET) imaging. Basically, it again puts into a variational framework the waveletvaguelette<br />
method <strong>of</strong> Donoho; it shows that wide classes <strong>of</strong> computationally efficient wavelet transforms can be used<br />
for tomography; and it gives examples that show that wavelet techniques are much more effective than the usual filtered<br />
back-projection method for PET imaging.<br />
This work has been supported continuously by the Office <strong>of</strong> Naval Research since 1990.<br />
