Hey guys, im trying to do skeletonization for this image using python 3.6.3 opencv.

image description

I'm hoping to use Guo-hall or Zhang-Suen thinning algorithms to skeletonize this image. Please advice me for python(3.6.3) opencv.

Which version of opencv? And do you have the contrib modules installed?

@Tetragramm hey im using opencv 3.3.1 , No im very new to using python.. I only have numpy and opencv2 installed.

Very simple!

from skimage.morphology import skeletonize

But please pay attention to this, the input parameter should be either 0 or 1, so you should do it like this:

ske = (skeletonize(thr_img//255) * 255).astype(np.uint8)

Sorry, i don't quite understand. I am new to python.. please advice me. Do i need to add extra whl for my python in order to use thinning algorithm in xmingproc?

you will need opencv_contrib package or you have to build opencv and opencv_contrib and install in your python version

Either the opencv_contrib package from your package manager, or you need to follow the appropriate tutorial HERE. You also need to include the opencv_contrib package in the build. When you download the source, there's a README file that explains how to do it, linked HERE.
