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

Accompanying code for "Extracting 3D Parametric Curves from 2D Images of Helical Objects", Sept 2016

This repository provides a MATLAB implementation for extracting a 3D parametric curve from a 2D image of a helical object. It also contains functions to "unwrap" or "straighten" images of curve-like objects according to their main structural curve.
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:

a.) Open MATLAB, right click project directory and add to path.
b.) Open main.m
c.) Change 'image' url.
d.) Adjust the parameters, as discussed in the paper.
e.) Run

Alternatively, call the relevant parts of code accordingly.
