<title>Physical Measures Of Image Quality And Their Relationship To Performance</title>

Abstract

The emphasis in this paper is on frequency domain measures of image quality. The development of a quality measure is illustrated with a series of studies using the optical power spectrum.Relationships with information extraction performance are used to evaluate the effectiveness of the resulting quality measures.The studies cover several image types: conventional photography, CRT display and digitized imagery.The status of physical quality measures, as tools for display development and evaluation, is assessed.
