New in GrowCut 3.0 (Sep 3, 2010)
- New Matting stage after the Refinement stage, which allows creation of soft/fuzzy edges with correct alpha-channel, instead of hard-edged cutouts of GrowCut 2.0
- Movable/dockable toolbars
- Support for host applications that do not have opacity channel via Alternative Output
- Selection version of the plug-in is no longer available; when needed, please create the selection from layer instead
- Improved user interface look
- GrowCut framework for faster creation of the initial markup instead of manually tracing the boundary with Edge Highlighter
- Undo/Redo functionality
- Edge Highlight Lasso tool
- Improved matting algorithm with adjustable smoothness
- Output into Layer Mask instead of alpha-channel
- Partial support for 16-bit and 32-bit images (matting algorithm is still 8-bit and downgrades the color-depth in fuzzy areas, but opaque areas retain their original color)
- Some minor bugs and memory limitations are fixed
