Toby Skinner Generative Art Pastels
'Pastels' by Toby Skinner


'Pastels' is driven by automated features extracted from an image using a combination of SURF, KLT, PoTrace and manual selection.

A voronoi graph is computed given these feature points, combined with the underlying pixel data from the original image we execute the core algorithm which generates flat colour (but low-alpha) squares.

Each square is technically a polygon, each side of the square beign sub-divided slightly to provide texture, each square also being layered a number of times with varying small pertubations to the position.

We calculate the size of squares from the voronoi graph, the small the square is, the more solid the outline.

Can this exact image be re-produced? No, the random pertubations to the square edges and positions will result in a slightly different image. However, given the same image, two outputs from this algorithm will retain the same key outstanding features.

Are there any other images on this website that were generated by this algorithm? Yes, this algorithm is used by Translucent and Dream with different parameter sets.

Is this a limited edition print? No
