Abstract

A comparative study of the effectiveness of algorithms for processing infrared images, namely, Fourier and wavelet analysis, analysis of principal components, polynomial fitting, and other types, has been performed with active thermal testing of metals and nonmetals and using optical, convective, ultrasonic, and eddy-current stimulation.
