I want to use Mathematica to generate a cartoon of a face. For example, some thing like this:

enter image description here

I think it can be done using Mathematica, but I really don't know how to do it. How can it be done, and what kind of a cartoon can Mathematica generate?

    $\begingroup$ Also, note that Mathematica won't zip up the guy's hoodie for you. The pictures don't match. $\endgroup$ – Verbeia Sep 23 '14 at 11:45
  • $\begingroup$ @Verbeia I know that. what I am looking at is the face only. $\endgroup$ – Algohi Sep 23 '14 at 13:28

Here is an idea based on MeanShiftFilter:

start = ImageCrop[ExampleData[{"TestImage", "Girl3"}], 200, Left];
step1 = MeanShiftFilter[start, 3, 0.05, MaxIterations -> 10]

enter image description here

step2 = Binarize[ColorNegate[DerivativeFilter[step1, {0, 1}]], 0.95]

enter image description here

ImageMultiply[step1, step2]

enter image description here

Obviously you can play with filters to get a different outline effect. Here is a quick Manipulate:

 With[{colorversion = 
    MeanShiftFilter[start, ms1, ms2, MaxIterations -> 10]}, 
    Binarize[ColorNegate[DerivativeFilter[colorversion, {0, 1}]], v1],
     Binarize[ColorNegate[DerivativeFilter[colorversion, {1, 0}]], 
     h1]]] ], {ms1, 1, 6, 1}, {ms2, 0.01, 0.1}, {v1, 0.8, 0.999}, {h1, 0.8, 0.999}]
