Detecting defects in adhesively bonded joints, using active thermography methods is very promising NDT testing method. In many cases, tests are made with agreed conditions, where a test object is always in specific place of IR camera view. Although, for needs of industry, system should be able to adjust Region of Interest in order to prevailing conditions. Therefore, it is necessary to develop appropriate method for this task. The paper describe one of the easiest attempt to separate foreground of an IR image sequence acquired by Lock-In Thermography (LT) and Pulse Thermography (PT). Proposed approach is based on segmentation and morphological operations. The IR image sequences of 11 various samples were used for this task. Obtained results show that elaborated technique of foreground object extraction is possible.
