Abstract
A method for identifying a defect such as a crack on a turbine rotor blade while the blade is in operation within a gas turbine engine, the method includes scanning the blade using an IR camera, identifying a leading edge or other line on the blade for a reference point, identifying a potential defect candidate on the blade by comparing the potential defect to a surrounding neighborhood in order to determine if the potential defect is an anomaly, and if the potential defect is an anomaly determine the structure of the anomaly in order to determine if the defect is a crack or a hole or a TBC spallation. The method computes a probability density for sub-regions in an image of the blade, conditioned upon the areas surrounding the sub-regions.
