Abstract

The Dual-Tree Complex Wavelet Transform (DTWT) is a relatively new signal processing tool that has the property of being largely invariant to subsample shifts in the signal being transformed. This property is particularly useful in many image processing applications. The presentation will briefly discuss two projects which use the DTWT to provide improved solutions to problems in the areas of medical image registration and video watermarking.
