Vincent van Gogh
We apply archetypal analysis to a set of 1154 artworks by Vincent van Gogh obtained from WikiArt. Since this collection is much smaller than the full GanGogh collection, we choose \(k=32\) archetypes.
Style Enhancement
We enhance the strongest (left side) and second strongest (right side) found in the image relative to the rest of the decomposition.
Free Style Manipulation
Interpolations between two archetypes on a grid. The archetypes are freely chosen, they are not necessarily present in the image decompositions before stylization. Indeed, this is perfectly possible to apply to natural photographs, as shown below. For each image, we vary \(\gamma\delta\) from 0 (middle) to 0.7 (inner 8 panels) to 0.9 (outer panels).
Image Decompositions
Archetypal analysis allows to decompose an image into its contributing styles. Below are some examples of these decompositions. The contributions of the archetypal styles are visualized in three ways:
- as a texture synthesized using the archetypal style (left column)
- as stylization of the image in questions, using a unit vector for each contributing style (top row)
- as a sum of the (strongest three) contributing images
