Ivo Dinov, Florida State University
Wavelets, Decision Theory and Image Analysis, II
In this talk we will try to combine knowledge from the areas of Wavelet Analysis, Decision Theory and Parameter Estimation to address problems arising in Image Analysis.
We will motivate the study by looking at the problem of quantifying the performance of different image-registration techniques. Following an approach by Donoho & Johnstone we use decision theoretical methods and least-squares estimates to develop a meaningful (in an "optimal estimator" sense) scheme for denoising, analysis and comparison of signals in wavelet space.
Along the way we will discuss Multi-Resolution Analyses, wavelets, the discrete wavelet transform and their properties.
We will propose a new approach for "soft-thresholding" on the wavelet coefficients, and will exploit its optimality characteristics (regular and asymptotic).
This is intended as a two-period presentation.
