Extracting 3D Parametric Curves from 2D Images of Helical Objects

Implementation of our paper "Extracting 3D Parametric Curves from 2D Images of Helical Objects"

• by Chris G. Willcocks, Philip T. G. Jackson, Carl J. Nelson, and Boguslaw Obara

Overview

This repository provides a MATLAB implementation for extracting a 3D parametric curve from a 2D image of a helical object.

Our project is split into 4 parts, as discussed in the paper:

1. Segmenting the helical object (Algorithm 1)
2. Straightening the segmented object (Algorithm 2)
3. Fitting a curve to a straight object (Algorithm 3)
4. Undoing the coordinate transforms

For general usage:

• Open MATLAB, right click project directory and add to path.
• Open main.m
• Change 'image' url.
• Adjust the parameters, as discussed in the paper.
• Run
• Alternatively, call the relevant parts of code accordingly.
