pointextract 0.0.53

Unwraps a circular surface through a topological transform

pointextract

Topological transforms by point sampling. Includes:

• Unwrapping circular and annular regions of images into linear or 2D arrays

Designed to unwrap 2D cross section images of 3D X-ray computed tomography scans. The transformation enables the surface of a circular object to be aligned for downsteam analysis and a topological transform.

Installation

You can install the package with:

pip install pointextract

Before using this package, ensure you have Python installed on your system. This package requires the following dependencies:

• numpy

Example

Simple example:

import pointextract
from skimage.io import imread

img_arr = imread('example.png')

ellipse = ellipse_detect(img_arr, sigma=2)

img_unwrap = unwrap_image(img_arr, ellipse, radial_distance=50, num_points=400)
