Can a computer draw like a human?

I have been studying and researching about Computer Graphics for more than 15 years. A great part of this time I have spent researching about professional artistic filters and effects.

I was always facinated by the way humans produce art, mainly drawngs and paintings. I have always tried to create math models and algorithms able to make drawings like ones made by human hands.

Now I got closer to my intention. I have created a new model to draw based on photos. Here some of the main reasons that make this algorithm work "like a human":

- the final image is made of thousands of small and delicate strokes (many people are used to draw this way);

- each stroke is carefully chosen (the calculations are made stroke by stroke);

- strokes respect and follow the photo geometry globally (on purpose or not, drawers usually act like that).

Below I show you a simple example. You can easily realize the strokes follow the geometry of the input photo in a similar way many drawers do.
