Rain girl

This is one of my favorite pics – a girl walking in the rain outside our first house. I’ve posted it previously, a couple of times.

I came up with an implementation of Aaron Hertzmann’s “painterly” non-photorealistic rendering algorithm. This recreates the source image by using simulated brush strokes of varying size, color and shape. It’s not a blurring or filtering of the source; it’s a recreation made in much the same fashion that a human painter would copy a picture: look at the source, choose a color, make a stroke which follows that color. Repeat until you’re done. As with a human painter, it starts with large brushes to get the background and large areas filled, then it refines the image with progressively smaller brushes.

This video is the algorithm in action, drawing the strokes (20 per frame, to save time). I told it to use short strokes.

The music is called “One Bird”. That’s me.

Here’s one of a pic of Adrian Belew:

Longer, thinner brush strokes.
