摘要：This letter proposes a nonnegative pattern separation model for eddy current pulsed thermography (ECPT) to automatically extract important spatial and time patterns according to the transient thermal sequences without any pre-training or prior knowledge. In particular, the method is scale-invariant such that large differences in surface emissivity, hot spots, and cool areas with dynamic range of thermal contrast can be extracted. Finally, an artificial slot in a steel sample with shining and black strip on the surface is tested to validate the proposed method.
