A vision-based line-tracking (VIBLITE) technique has been proposed for uplift measurements of railway catenary systems in front of noisy backgrounds. The file contains MATLAB code with example images for processing. The Line-tracking technique is designed for detecting and tracking a linear object, e.g., a railway catenary wire. The technique is based on a coarse subset and line search and subpixel centerline detection. Vertical displacement response of the linear object can also be obtained. The principles are described in detail in reference: Tengjiao Jiang, Gunnstein T. Frøseth, Anders Rønnquist, Egil Fagerholt.

A Vision-Based Line-Tracking Technique (Matlab version with tutorial)

Introduction

The line-tracking technique is an image-processing technique and is designed for detecting and tracking a linear object, e.g., a railway catenary wire, from noisy backgrounds. The technique is based on a coarse subset and line search and a subpixel centerline detection. The principles are described in detail in the following article [1]. Displacement response of the linear object can be obtained.

The files contain MATLAB code with a tutorial and example images for processing.
