Abstract:Selection of specific frame from transient thermal image video to maximize the contrast of thermal variation and defect pattern from complex geometrical samples remain a challenge. In order to accurately find anomalous patterns from the transient thermal pattern for defect detection and further quantitative NDE, this paper employs a single channel blind source separation algorithm. This method enables spatial and time patterns to be extracted according to the whole transient response behavior without any training knowledge.
