Wavelet Frames: A Filter Design Perspective

The design of over-complete wavelet transforms (or frames) leads to several problems in filter design. The properties the filters must satisfy depend on the type of wavelet transform. This talk will look at the filter design problems coming from the double-density and dual-tree complex wavelet transforms, and illustrate how certain allpass filters are needed. We will also see that in 3D the complex wavelet transform gives a motion-based multi-scale decomposition for video.
