Extra Polynymous
Voronoi diagrams are great, so let’s use them to stylize images. First, let’s just throw a bunch of points on an image, and compute the Voronoi diagram. Then for each cell, we fill it with the average or median color within: Hmm. That’s not great. It doesn’t pay attention to the edges at all, and […]
Previously, I split an image into a bunch of rectangles. What about using triangles? This requires more thought, as it’s a little trickier to divide up the plane using triangles. The natural solution is to keep track of a set of vertices, then use a Delaunay triangulation to split up the image. First, let’s do […]
I want to represent an image with a bunch of rectangles. Let’s say that each shape has constant color, as a start. First, fill a rectangle with the average color that it covers. That’s the initial approximation. Wherever the error in a rectangle (between the original image and the approximation) is too big, subdivide that […]
