Radiometric Enhancement of Images

Chapter

Abstract

Image analysis by photointerpretation is often made easier when the radiometric nature of an image is enhanced to improve its visual characteristics. Specific differences in vegetation and soil type, for example, may be brought out by increasing the contrast of an image. Highlighting subtle differences in brightness value by applying contrast modification, or by assigning different colours to different brightnesses in the method known as colour density slicing, will often reveal features not otherwise easily seen.
