I was recently asked if there was a way to partition an image into regions based on shape or color. And then work on the individual regions.
So if you want to do this automatically as a part of the auto paint process, you can do this using the path start regionization features. The Path Start control panel has a number of different path start regionization generators. Any generator that include Regionize in it's name is a path start regionizer.
Path Start Regionization has been discussed in a number of articles.
Here's a link to some Studio Artist News blog articles on regioniation.
Here's a link to some Studio Artist Tips on regionization.

Here's an article that discusses the different path start regionization generators in the context of building photo mosaic imagery.

You can also use selection is Studio Artist to select regions, and then mask an action or interactive effect based on the selection acting as a mask.
There's also a special selection generation option in the Canvas : Selection : Set to menus called Regionized Source. This menu command breaks down the source image into regions and then places that result in the selection buffer. Any modulation option in the paint synthesizer that has a local selection option will mask to whatever local selection region it is located in.
You could also build a much more extensive set of source regionization effects by using the appropriate image processing effects in Studio Artist and then routing the output of the effect that generated the regionized source image into the selection buffer (as opposed to the normal replace composite that places the output in the canvas). An effect like the Watershed Regionize image operation effect would be a good place to start. Or the Vectorizer using it's raster canvas render option.
