Thermography pattern analysis and separation for NDT&E

This is a simple demo code to analysis inductive thermal patterns for defect detection in NDT&E

The code is about the thermal pattern separation which more details can be found in the paper of "Bin Gao, Libing Bai, Gui Yun Tian, W.L. Woo, Yuhua Cheng “Automatic Defect Identification of Eddy Current Pulsed Thermography Using Single Channel Blind Source Separation”, IEEE Transactions on Instrumentation and Measurement, vol.63, no.4, pp.913-922. 2014". The method allow us to automatically extract valuable spatial and time patterns according to the whole transient response behavior without any training knowledge
