SIOX can by definition only extract things from a background if the foreground color is sufficiently different. After all that is how the algorithm decides what to separate. So what you suggest here sounds more like adding a different separation algorithm and not like improving SIOX. But of course I might just have misunderstood you. The SIOX tool has several areas where it is lacking. The most notable is that it does a binary separation. Either a pixel is foreground or it is background. This causes jaggy edges and makes it necessary to do manual post-processing on the selection. The SIOX team around Gerald has suggested several improvements that would help to improve this. Their papers describe a refinement brush that should be used on the selection boundary to improve the results. It would be nice if this could be added to the GIMP SIOX tool.
