Paper Abstract

The importance of image restoration is increasing with the widespread use of imaging systems in various sectors of modern technology. However, as far as the quantitative application of computerized Infrared Scanning Radiometers to the study of thermo-fluid--dynamic problems is concerned, it seems that the image restoration is not addressed in a satisfactory way by the currently available commercial systems. The aim of the present paper is to yield a contribution in this direction. While defining a degradation model, in particular, the effects (if any) due to digital sampling are also taken into account by means of a cascade model including both imaging and sampling effects. Two heat transfer applications (in presence of natural and forced convection) are discussed.
