Interactive Signal and Pattern Analysis and Recognition Systems (ISPARS). Users' Guide.

Abstract

This report is a functional description and user's guide to the interactive Signal and Pattern Analysis and Recognition Systems (ISPARS). ISPARS is a loosely integrated interactive graphics software system, installed on a PDP11/45 computer system, for processing sampled signal waveforms and determining the pattern classes into which waveforms may be separated. ISPARS capabilities for signal analysis include segmentation, spectral decomposition, transformation (Filtering), normalization, and characterization of signals. Signal analysis is viewed as a means of eliminating redundant information in the signal and thus extracting significant features. These features form the input to the pattern analysis procedure which permits the construction of algorithms for clustering and classifying feature strings. ISPARS affords the user a convenient, flexible means of visualizing and exploring a sampled data stream by employing interactive displays of complex transformations, easy parameter modification, convenient data stream control, and a simple, concise command language.
