Urban Pattern Recognition and Image Color Discrimination with TV Waveforms and Computerized Matrix Analysis and Mapping.

摘要

The report presents concepts,instrumentation techniques,methodology and experimental results of investigations which evaluated feasibility of applying black and white television and waveform signals to purpose of quantitatively recognizing,discriminating and mapping geographic patterns in imagery or in electronic signals via which such are transmitted. Colors in aerial photographs,or the environment,are discriminated and identified by combination of relative signal values when filters are used to gather the signal data. Four or less filters were required for 96colors tested. Consequently,phenomena may be identified by color. Recognition of terrain,or 'land use',patterns found in an urbanized coastal environment is feasible. The technique is applicable to any pattern at any scale. Annotated bibliographic file of articles on computerized image processing published in geographic and photogrammetric journals from 1963to 1973is also presented. (Modified author abstract)
