'Statistical methods for automatic crack detection based on vibrothermography sequence-of-images data' by M. Li, S. D. Holland and W. Q. Meeker: Discussion 2

摘要

The paper written by M. Li, S. D. Holland and W. Q. Meeker [Applied Stochastic Models in Business and Industry] presents statistical methods for automatic Crack detection based on vibrothermography sequence-of-image data. In particular, a matched filter used to increase the signal-to-noise ratio is developed. The review gives suggestions about physical approach and detection criteria.
