Creating stripped portraits

Hello to all. I am trying to work out the logic of how striped pattern for a portrait can be generated using an image in grasshopper. I just need the logic so that I can work on a script. I am attaching two reference pictures of what I am trying to achieve. Any help or guidance would be appreciated. [u5][download]
