Abstract

Results of using the standard processing algorithms (spatial filtering, linear and non-linear transformation, histograms, etc.) to enhance the quality of thermograms in infrared NDT are discussed. More sophisticated algorithms have been developed to suppress the emissivity noise and non-uniform heating-cooling effects. In addition, some new approaches to thermal tomography are presented.
