Low-rank sparse principal component thermography (sparse-PCT). Comparative assessment on detection of subsurface defects
Infrared Non-destructive Testing (IRNDT) applications are unequivocally expanded and portend a commodity to
improve the quality of defect detection in different fields such as aviation and industrial methods to arts and
archaeology. The proposed approach focuses on the application of low-rank sparse principal component thermography
(Sparse-PCT or SPCT) to assess the advantages and drawbacks of the method for non-destructive
testing. For benchmarking the approach, two types of infrared image sets are tested: the Square Pulse
