Annotation: The article is devoted to passive information systems used to identify remote objects in the infrared infrared wavelengths based on calculated thermal signatures. It is noted that the objective characteristic of an object free from the influence of background radiation is thermal contrast. However, in order to identify thermal objects, it is often important to obtain not integral estimates of the IR signature of an object, but the spatial structure of this signature on the observed surface. In such cases, the main information feature for identifying the type of object is precisely the two-dimensional distribution law determined by the surface temperature, and not the integral indicator of the radiative flux emitted by the object. A method for analyzing the temperature distribution on the surface of a remote object, forming equal temperature zones on the image and using the results of processing the received information is proposed to identify the object. In order to form these zones (layers, segments), a base element is selected and a comparator is used to compare the image elements, which reduces processing time by eliminating the selection operations of image elements of equal temperature.
