Statistical Techniques for Signal Processing.
Abstract
This report describes the results obtained during the grant year 1 November 1982 to 31 October 1983. References are made to twelve publications produced or in preparation. The research supported was in the area of robust signal processing, particularly nonlinear filtering and smoothing. Results were obtained on quantization of filters and on multiple-input robust matched filters. Considerable progress was made in the area of nonlinear filters and smoothers, where it appears that generalizations of median filters may be of considerable practical significance in applications such as speech and image processing. In addition, some further analytical results have been obtained on the statistical properties of median filter outputs for Markov models on signal-plus-noise. Results on output power spectral densities for white inputs have also been obtained for M-filters based on robust M-estimation. (Author)
