Multiresolution representations using the auto-correlation functions of compactly supported wavelets, (with G. Beylkin), IEEE Trans. Signal Processing, vol. 41, no. 12, pp. 3584-3590, 1993; Erratum: vol. 45, no. 3, p. 768, 1997.

Abstract

We propose a shift-invariant multiresolution representation of signals or images using dilations and translations of the auto-correlation functions of compactly supported wavelets. Although these functions do not form an orthonormal basis, their properties make them useful for signal and image analysis. Unlike wavelet-based orthonormal representations, our representation has (1) symmetric analyzing functions, (2) shift-invariance, (3) associated iterative interpolation schemes, and (4) a simple algorithm for finding the locations of the multiscale edges as zero-crossings. We also develop a non-iterative method for reconstructing signals from their zero-crossings (and slopes at these zero-crossings) in our representation. This method reduces the reconstruction problem to that of solving a system of linear algebraic equations.
