Abstract
This paper presents a method for eliminating structural noise in scann ing thermal viewers caused by sensitivity inhomogeneity of a photodete ctor device. The thermal field of the observed scene is directly used as a source of information on the degree of sensitivity inhomogeneity. The iconic approach consists of using digital image-processing method s to calculate the compensation factors from the output image of a the rmal viewer. Experimental results of the application of the method to test images and real images are presented. (C) 1997 The Optical Societ y of America.
