Deep-Feature-Matching-Based B-Spline Scale Correction Method for Nonlinear Distorted Images

open access: yesIEEE Access
Images collected by linear scan cameras are nonlinearly stretched and compressed due to the speed regulation of high-speed trains. This condition changes the shape of objects and thus considerably increases the false and missed alarm rates for the ...
