I contributed today's Square Root of Minus Garfield strip:
Taking "remixed Garfield strips" fairly literally, I created these three strips using a generalisation of the Dissociated Press algorithm to two dimensions. Here is how it works, more or less:
- Construct a source image consisting of all regular non-Sunday Garfield strips from 2007, forced into a common 216-color palette. (Avoid dithering; that gives bad results).
- Generate the pixels of the output image in pseudo-random order, as follows:
- Set N=32 and find the N pixels closest to the target pixel coordinates that have already been generated.
- Locate all pixels in the source image that have exactly the same colours in the same relative positions as the neighbour pixels found in step 3
- If no source pixels were found in step 4, decrease N by one and start over from step 3.
- Otherwise, set the target pixel to the colour of a randomly chosen one among those found in step 4.
I generated a dozen-odd images – each takes about 6 hours of CPU time – and selected the most interesting ones. They tend to be more chaotic than I had hoped (and increasing the initial N does not seem to help), but still they are not complete failures.
