Abstract
Thermal response of a turbine component to application of thermal stimuli is automatically analyzed by regions of interest. Each region may be analyzed for conformance for a number of thermal response metrics, in an absolute sense, and/or relative to each other. The thermal response metrics may include the temperature threshold a particular region (e.g. the reference/primary region) exhibits a critical response size, and that the sub-region achieving the critical response size at the temperature threshold also has a critical shape. The analyses may be performed using the pixel values of the constituting pixels of a picture frame of the turbine component's thermal response. A binary passed or failed conclusion may be reached based on the results of the automated analyses.
