Again i'm trying to approximate pixel art from a picture using feature detection to refine results. but this time i'm also doing color reduction to 8 colors. and i think it looks great

  Currently i'm trying to generate pixel art from images by approximating the original images with rectangles using simulated annealing (similar to http://alteredqualia.com/visualization/evolve/). But i'm using a more complex fitness function that involves optimization for visual features using feature detection techniques.
The upper row of the video shows the current approximation and the original image and the lower row shows a visualization of "good" features found in both pictures.

Way faster and precise approximation of a sobel filter
The video shows the approximation process of a sobel edge detection filter using a genetic algorithm. The first row shows the current search result and the seconds row shows the target filter with the picture on the left, the dft in the middle and the dft in binarized form on the right.

I'm using a genetic algorithm to approximate a series of convolutions which try to mimic a given effect. In this example it tries to learn a 8x8 blur effect generated with ImageMagick (convert -blur 8x8).
The upper images in the video show the current approximation and the magnitude spectrogram of its discrete fourier transform (DFT).
The lower images show the target image and its DFT.
Only results of the best candidate of each generation is shown in the video.

  built an IR midi paddle @metalab. we are using the IR proximity sensors for guitar/blues harp effects and the buttons for looper control.

This scenario is the continuation of the previous "Deliver the ammo 1". It's sole purpose is to check if they actually seek the facilities and enemies because sometimes they are actually reacting to rather strange circumstances. Changing scenario dimensions is a good check for that.

Last week i changed the rules fundamentally. Now the space ships have finite fuel and ammo and they die when they are out of fuel. So i added "facilities" which they must use to recharge themselves.
To make them learn to recharge i gave them only a very small amount of fuel and no ammo in the beginning - so either they find the facility quickly or they die.
Additionally enemy facilities may be captured if the amount of enemy ships in range is greater by 3 than the amount of friendly ships in range but neither have i adjusted the fitness function nor did i train them yet to do so.

Lately i spend a lot of my time working on optimizing game/learning performance. In this video is it only takes 10 generations to learn the difference between an enemy and a friend and the basic movement required to attend this scenario. Also the simulation runs quiet fast.
