Hi all, I have tested again i.segment and discovered that for the NC Landsat 2000 imagery the module takes nearly 7 hours for reasonable segmentation. The i.segment.xl module does the same in 10 seconds. The region consists of 250 000 cells, not so much. In the documentation it says that processing the entire ortho image takes about a day. With the xl version it takes about 10 minutes. I am going to move the xl version to trunk and keep the original GSoC version in addons for reference.
