cpselect2 1.0.6

Matlab's cpselect alternative for Python

cpselect

Alternative to Matlab's cpselect tool

Continuation of the cpselect project from Tobias Hoffmann

I have fixed the bug caused by the newer version of matplotlib. I have also asked if this project could be maintained by some other larger libraries like opencv or scikit-image, but none of them are able to do so!

I will try to keep this project up to date since some toolchains depend on it, but my Qt knowledge is quite rusty...

It would be amazing if we could switch from Qt to streamlit or dash for displaying the GUI in the browser! So if someone has an idea, please open up an issue for discussion :)

Prerequisites

You will need to have the following packages installed:

• matplotlib (tested with 3.0.1)
• Pillow (tested with 5.3.0)
• PyQt5 (tested with 5.11.3)

Installing and import

Install the package using pip (since cpselect is already taken, I have opted for cpselect2)

pip install cpselect2

and import it with

from cpselect2.cpselect import cpselect

Using cpselect

Just call function cpselect. The function takes two inputs, two strings with the path to your pictures.

controlpointlist = cpselect("path/to/image1", "path/to/image2")

It will return a list object, which contains a dictionary for each control point.
