I will use the following Mathematica script, to validate results: image = // ImageData how organic/smooth the cell shapes look.how well the algorithm works with very restrictive parameters.how well the algorithm works on different kinds of images (paintings are probably generally easier than photographs).how well the original images are approximated.Voters are encouraged to judge answers by This is a popularity contest, so the answer with the most net votes wins. I assume that parameters around N ≥ 500, P ~ 30 would be similar to real paint-by-number templates. Also, feel free to use other test images, if you find something nice. Alternatively, put thumbnails in your post and make them links to larger images, like I did above. If you want to show a large number of results, you can create a gallery over on, to keep the size of the answers reasonable. Please include a handful of results for different parameters. Here are a few images to test your algorithm on (mostly our usual suspects). The following image has P = 6 and N = 11: ![]() Just to visualise the parameters, here is a very simple example (for no particular input image showing off my mad Paint skills). In short, you are to approximate the input image with only N flat-shaded/solid-colour areas and P different colours. Pixels touching only at a corner are not considered contiguous. The output image should have the same dimensions as the input.Ī cell is defined as a contiguous area of pixels which all have the same colour. ![]() Your algorithm does not have to use all P colours and N cells, but it must not use more than that. the maximum number of distinct colours to use), and N, the maximum number of cells to use. Along with the image, you're given two parameters: P, the maximum size of the colour palette (i.e. Your task is to generate a version of this image, which looks like it was painted using paint-by-numbers (the children's activity, not nonograms).
