Toward A Measure Of Image Enhancement
Leo M. Levi · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1989
Image processing, in general, and image enhancement in particular, have been active topics for over 25 years, and much is known about them. However, it appears that quantitative measures for image enhancement, as such, have not been formulated, even though the theory necessary for such a measure has been developed. Such a measure will be presented and applied to a representative form of image enhancement. Simple enlargement may serve as a good illustration. Such phenomena as image degradation due to excessive magnification, which are well known qualitatively, are put on a quantitative basis.
