Abstract : In the past year, support from this contract has been acknowledged in 14 published articles and one book. New characterizations of wavelets have been found leading to new constructions and new wavelets. Advances were made in the theory of multipliers in Fourier analysis. Wavelet technology was transferred to four commercial products: liquid crystal matrix display driver simulation, de-noising software for medical images, image compression algorithms for the FBI, and image analysis software for automatic finger print identification systems from compress images. One book and seven technical reports on new algorithms have been submitted or are in preparation. One patent was issued, US No. 5,384,725, "Method and Apparatus for Encoding and Decoding Using Wavelet Packets" (R. R. Coifman, Y. Meyer, M. V. Wickerhauser). An improve version (AWA 3.0) of and earlier commercial software package, the "Adapted Wavelet Analysis Library", was released. Travel funds supported about one dozen seminars, colloquia and minicourses in Australia, Croatia, France, Germany, Italy, Spain and the United States.
