Deep learning-based sustainable subsurface anomaly detection is the perceiving of thermographic research. Subsurface detection of an anomaly in various materials using deep learning increases reliability. This article aims to describe a method that uses thermal wave imaging to identify subsurface anomalies in materials. The proposed method is based on the experiments that were carried out with different kinds of samples and have been compared to other modern techniques for detecting subsurface anomalies. Subsurface anomalies visualized using the proposed deep learning method give better visualization, and the results were compared to that of contemporary approaches. In addition, region-based active contour segmentation-based detection is also proposed for the GFRP sample.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
