Image-triangulation (delaunay and voronoi)

Hacker News

Hey guys, it's my first post here, but I've been reading for a couple of months. And right now I am ready to share some stuff I made. Please feel free to ask, criticize or suggest alternatives :) https://github.com/MauriceGit/Delaunay_Triangulation A couple of months ago someone here (don't have the link anymore) inspired me to finally sit down and implement a delaunay-triangulation and voronoi from scratch. What the python-script does is: - take an image, extract points dependent on the contrast and color difference of the image (more points on edges or in contrast-rich parts). - triangulate the points with a delaunay-triangulation (from scratch). - transform the delaunay-triangles into voronoi-regions. - render the triangles and voronoi-regions into new images with the average color for each polygon (from the original image). The delaunay-triangulation runs in Omega(n logn) but I'm not 100% sure if also in O(n logn). The transformation into voronoi-regions runs in O(n). Please tell me what you think :) Best regards Maurice
