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.
