Claim One:
1. A process for matching two related but transformed signal waveforms representative of sensor outputs in a particular application domain, said process comprising the steps of: selecting criteria, associated with the particular application domain, for use in the determination of significant points of interest, type sets of allowable types of point matches, type match valuation, match windows, disparity windows, and disparity similarity valuation; identifying significant points of interest in each data set; determining positional offset information and type information for significant points of interest in each data set responsive to said criteria; determining a match window for each significant point of interest responsive to said criteria; locating and determining match values for all allowable matches between significant points in the two data sets, within respective match windows; determining disparity windows for all significant points in the two data sets; determining composite similarity values for each allowable match to a particular significant point in the first data set, responsive to the positional offset information for each allowable match to said particular point and to the positional offset information for correspondingly offset allowable matches for other significant points in the first data set, for such points within the disparity window with said particular point, responsive to the match values; determining a best match for each said particular point within the first data set corresponding to the allowable match point in the second data set having the maximum composite similarity value for the respective particular point, responsive to the match values and the composite similarity values; and matching the two signal waveforms responsive to the criteria and the determined best matches.
