Comparison research on infrared thermal wave image sequence processing technology

The infrared thermal wave image processing technology is one of the new key technologies of nondestructive testing. The paper summarizes the typical infrared thermal wave sequences image processing algorithms, introduces the basic principle of each algorithm, and presents the experiments and three-dimensional visual display. The image processing results are quantitatively evaluated and compared by the rules such as Entropy, Spatial Frequency (SF), Root-Mean-Square-Error (RMSE), and so on.
