Intelligent recognition of defects in high‐speed railway slab track with limited dataset
Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 6, Page 911-928, 15 March 2024.Abstract During the regular service life of high‐speed railway (HSR), there might be serious defects in the concrete slabs of the infrastructure systems, which may further significantly affect public transportation safety. To address these serious issues and fulfill the regular functions of HSR, the traditional methods for railway engineers involve ...
