Linear discriminants and image quality
Image and Vision Computing, 1992The use of linear discriminant functions, and particularly a discriminant function derived from the work of Harold Hotelling, as a means of assessing image quality is reviewed. The relevant theory of ideal or Bayesian observers is briefly reviewed, and the circumstances under which this observer reduces to a linear discriminant are discussed.

The steps in reproducing evaporograph images are discussed. An analysis of signal and noise is given for different stages of the evaporograph process. The factors which limit the threshold sensitivity and resolving power of the evaporograph transducer are determined.

A Multidistortion Database for Image Quality
2017In this paper we introduce a multidistortion database, where 10 pristine color images have been simultaneously distorted by two types of distortions: blur and JPEG and noise and JPEG. The two datasets consist of respectively 350 and 400 images, and have been subjectively evaluated within two psycho-physical experiments.

[The quality of the roentgen image--a recommendation for quantifying image quality].
Rontgen-Blatter; Zeitschrift fur Rontgen-Technik und medizinisch-wissenschaftliche Photographie, 1987A proposal is worked out to express x-ray image quality by means of a meaningful and practically useful numerical system. Attennations have been selected in such a manner that whole numbers of Quality Value figures ranging from -10 to +60 result in meaningful associations with radiological indications.
