Release: Cict and Ciff

Today i've moved useful code that i initially wrote for other projects (ColorMorseCode and PixelStencil) into two litte CLI tools. Maybe someone finds it interesting or may even have immediate use for them:

Ciff (https://github.com/kallaballa/Ciff)
Calculates the difference between two RGB colors using the CIEDE2000 color difference metric

Cict (https://github.com/kallaballa/Cict)
Translate color values (24bit RGB hex) to human readable names

Lazzzored the pixel stencils for the @metalab main room.
That's what it will look like: http://kallaballa.soup.io/post/596918792/metalab-pixelart-by-me

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.
