Deep Learning (Fast R-CNN)-Based Evaluation of Rail Surface Defects

open access: yesApplied Sciences
In current railway rails, trains are propelled by the rolling contact between iron wheels and iron rails, and the high frequency of train repetition on rails results in a significant load exertion on a very small area where the wheel and rail come into ...
