Percentiles of Garfield: 2009

Strip by: Henning Makholm

{A textured, blurry, impressionistic strip, dark on the left, light on the right.}

The author writes:

Take all 313 regular (non-Sunday) Garfield strips from 2009. Crop them gently to be exactly 175 pixels tall each, and stack them atop each other. At each point in the image frame there's a stack of 313 pixels; pick up this stack and break it into 313 red values, 313 green value, and 313 blue values, forgetting which date each value came from. Then take the median for each colour channel (that is, the 157th brightest sample, which is also the 157th darkest). Assemble those medians into an image. You get something vaguely similar to Colour-Averaged Garfield.

Now change the procedure slightly. Instead of the median at each point, take a percentile determined by the pixel's horizontal position within the image. At the far left you take the darkest sample in each stack, in the middle the median, and at the far right the brightest one, and so forth. This strip is the result.

There's a fascinating progression of textures: from gritty and cracked, to mouldy and amorphous, to impressionist frosted-glass effects, to wispy pastels, to nothing.
