To improve the ability of eddy current nondestructive evaluation to characterize fatigue cracks in multilayer structures, a model-based image processing approach is presented that fits approximate models based on first-principles to image data. Model refinements are also presented that address error associated with adjacent holes and poor hole centering due to cracks. Using this approach, improvements in the visual representation of image data for crack detection and the potential for characterization were demonstrated. [ABSTRACT FROM AUTHOR] |
