In a vectorized image you want not only a realistic look but if possible only a few large regions to keep the number of polygons to a reasonable number. A usual 8 bit color image with 256^3 possible colors has in the worst case a different color for each pixel. The first thing one has to understand is that color vectorization happens in multiple scans, which means regions of equal color will be transformed in a polygon-representation. In the following sections I explain what steps are necessary to vectorize a color image in Mathematica. The only question was, whether it gives reasonable results. Then I read about how this is done in real applications and read the documentation to Potrace which is the underlying tracer of Inkscape.Īt this point it was clear to me, that we can achieve this with the tools included into Mathematica. I stumbled over this issue while thinking about this answer here where in my opinion a high quality vectorizer would be of great help. With good CPU and memory resources even in a very high quality.
