A Study of Two-Dimensional Recursive Digital Filters and a Study of Improved Statistical and Non-Destructive Testing Methods of Failure Prediction in Brittle Materials.
Abstract
Research efforts covered by the subject contract have been directed toward the stability and synthesis problems for two dimensional digital recursive digital filters. Such filters are advantageous when a premium is placed upon computer storage or computation time. Previously defined results on stability analysis have been refined and a revised paper has been submitted to the IEEE Transactions on Circuits and Systems for publication. This research effort will continue to address this complex problem. Approximately circularly symmetric lowpass, highpass, bandpass, bandstop, low frequency boost and high frequency boost filters have been designed. Evaluation of these filters with actual images of various types need to be addressed and has been proposed as a follow on to the effort described in this report.
