New Algorithm based on the Hough Transform for the Analysis of Pulsed Thermographic Sequences

The automatic detection of subsurface defects has become one desired goal in the application of Non Destructive Techniques. A new algorithm based on the Hough Transform, is proposed to reduce human intervention to a minimum by Pulsed Thermographic. The final result provided by this algorithm is an image showing the different defects without having attended to parameters so determinant in other algorithms as the delayed time of the first image or any subjective point of view in the analysis.
