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.

Identity filter

Setting kappa to 0 works best for the identity filter. However, you get interesting collage-like results with larger values.

Blur filter

: ::
Unfiltered source (A)
Filtered source (A')
Unfiltered target (B)
Filtered target (B')

Emboss filter

: ::
Unfiltered source (A)
Filtered source (A')
Unfiltered target (B)
Filtered target (B')
