Abstract

A multiresolution analysis based on wavelets is particularly effective for signals with marked discontinuities, such as microcalcifications produce in mammograms. The projection methods that generate the resumes and details can yield an entire family of orthonormal bases, or wavelet packets, which can be superior to wavelets for certain classes of signals. Results of applying wavelet packets to snippets from several mammograms are presented as a method of data compression, allowing reduction of the digitized data before applying pattern recognition techniques.
