The applicability (advantages and limitations) of IR-images and their scientific value are determined in the technical practice by the type of the technical phenomenon investigated; consideration of rules of IR-optics during the IR-image-taking; proper selection of ambient parameters. Under optimum conditions, the IR-image will contain all important information on the thermal character of the temperature field of the examined object or phenomenon. As a consequence, the evaluation of IRimages,

In the actual practice of IR-image analysis one may choose between three general methods, however their relative advantages and disadvantages must be decided in the light of the tests being done. The first is the traditional phenomenological analysis [1]. Two new methods serve for mathematical evaluation of temperature fields: the histographic analysis, i.e. the application of the distribution curve of temperature histogram for process monitoring [2] , and the mathematical filtering of IR-images to reveal the sites of highest temperature or of the largest temperature alterations [5],[6]. This paper presents these practical methods of IR-image analysis in the field of building engineering [4].
