Center of trace algorithms for extracting digitized waveforms from two-dimensional images

Lee, J.W.

A class of recording instruments records high-frequency signals as a two-dimensional image rather than converting the analog signal directly to digital output. This report explores the task of reducing the two-dimensional trace to a uniformly sampled waveform that best represents the signal characteristics. Many recorders provide algorithms for locating the center of trace. The author discusses these algorithms and alternative algorithms, comparing their effectiveness.
