Future Work

Before any new features I'd probably spend some considerable time working on improving the way bordering regions blend together some of the aliasing artifacts that can happen. I've worked a lot on this but haven't found something I love.

Due to region blending, there is a reduction in saturation in the resulting image. An accurate fix for this would be nice.

It would be cool to have faster close-up previews while you tweak settings.

Better tools for guided color: paint your color, automated color sets...

Guided parameter selection: pick which image you like and the algorithm finds things similar.

Incorporate edge-detection to bring out more detail. Also, find more interesting ways to post-process the images. Currently I blend in lights/darks but something more sophisticated could be interesting.

Jittering regions—somewhat randomly increasing or decreasing color properties could produce some interesting effects.

Incorporate a built-in image-to-image-feedback-loop.

Use an image for warping data.

More intuitive parameters, more presets and automation.
