image analogies: toy filters
Here are some results using image analogies to learn simple filters. While we would not recommend using image analogies in these cases (since faster algorithms exist), these tests show that the approach works in simple cases.
Setting kappa to 0 works best for the identity filter. However, you get interesting collage-like results with larger values.
