Should work on after effects now

It's sure it is good for hairy contents. I am not sure if those images will be  easier cases for classical mosaic methods or not. I am thinking to use Barbara's examples to guide color choices and shape maps.

Colored effects

Building and tree examples

Current process for previous results

Better for images with strong direction. Compared with previous results, for images like Lena, it seems long slivers work better than small regions.Also it looks sometimes we should keep the curved lines.Should have density control.
