Rail track extraction from the image can be used to determine the position of the rails ahead of a train, which is one of the fundamental tasks for vision-based driver support systems in railways. This paper introduces a method that extracts rails by matching the edge features of the real image to the candidate rail patterns which is parameterically modeled, and the geometric constraints of the rail...

The presented feature is a modification of SIFT descriptor taking into account of the characteristics of handwritten Chinese...
