This paper aims to present a study on the effects of thermal contrast in various external wall’s composite finishes on estimated debond size by using passive infrared thermography and a modified gradient algorithm. The effects of thermal contrast on debond size estimation by the proposed method were evaluated under 2 conditions: different finishes materials and changes of heat absorption during a 13-hr diurnal cycle. This study reports a quantitative investigation of detectability by comparing its estimated size with actual size.
