Delicate Image

We looked earlier at filters applied to the array of values holding the colour information for the Mandelbrot or Julia fractals.

Instead of smoothing the image, we instead use a filter which highlights edges, called a Sobel filter.

I love this image that that results from applying the Sobel filter to a Julia set. I love how it is delicate, detailed and yet has it's own inherent coherent structure. Click on it to show a fuller image.

Amazing that this essentially comes from a very simple iterated function z2+c.  And it's generated by the simple code we develop in the book.

I love it so much it's going to be the cover of the book!
