Inductive thermography is an emerging nondestructive testing and evaluation (NDT&E) technique and has been applied for a wide range of conductive materials. This research sets out to propose the thermal pattern separation and analysis of inductive thermography. It specify: 1) The fundamental understanding of inductive thermography and related basic NDT&E methods; 2) The principle of pattern separation algorithms and how they link to inductive thermography NDT&E; 3) The spatial-transient thermal pattern separation algorithm to automatically extract valuable spatial and time patterns to...
