Data Acquisition and Analysis for Camouflage Design

Abstract

The report describes efforts to measure the spectral characteristics of various vegetative terrains under sunlighted and overcast conditions, both verdant and dormant, using a photographic approach. Exposures taken through narrow bandpass filters were scanned for densitometric data which were reduced to tristimulus values for individual picture elements. Neighboring pixels of similar chromaticity characteristics were clustered to produce a facsimile of the original scene in 3, 4, or 5 average representative colors in CIELAB notation with spectral reflectance factors available.
