Abstract
Density, contrast, and contrast frequency were tested as textural attributes of wheat, sorghum, alfalfa, wheat stubble, and weeds, all crops having similar average density values on multipolarization K-band radar imagery but dissimilar plant geometries. Fifty-three microphotographs of fields displayed on Hedernheim (HH) imagery were scanned with a transmission densitometer, and contrast frequency values were derived. These measures did not yield significantly more information than that obtained in previous studies. It is, nevertheless, felt that texture and its associated attributes can often serve as reliable discriminants of crops and other areal extensive objects and contribute to the solution of automatic pattern recognition problems.Keywords
