Pixel Problems.

Abstract

The exploitation of airborne and satellite-mounted multispectral cameras for the acquisition of terrain information depends upon a detailed understanding of the way in which images are formed by scanner systems, and upon methods of manipulating the radiance values that actually comprise the primary record from which the image is derived. Items discussed include: geometric distortions of the images; relations among pixel size, resolution, and contrast; variations in image geometry caused by mismatches in phase and alignment of pixel arrays; variations in image geometry caused by scanning geometry; and variations in image geometry due to pixel shape.
