PRENONORMALIZATION OF PHOTOGRAPHIC RECONNAISANCE DATA.
Abstract
The results are described of a research program conducted to develop techniques for the processing of photographic data into a form suitable for use with an adaptive memory type of cognitive system. The particular adaptive system to be considered is a conditioned-reflex system called CONFLEX I. The requirement of context analysis caused efforts to be directed toward the general problem of two-dimensional signal analysis. The problem of transforming the raw image data in a manner invariant to image translation and rotation was attacked by analysis of the integral scanning process which extracts video data in a manner which preserves essential aspects of image continuity and spatial relationships of objects in a scene. Since the integral scan sequence is an extrapolation of a special form of spatial frequency analysis, the task of processing the resultant waveform to generate the desired image transformation reduces to a two-level harmonic analysis of the integral scan waveform. The resultant transformation of image data provides the necessary input to an adaptive system which can classify the superimposed ''signatures'' of selected or composite objects. (Aurthor)
