Hi, I executed the examples in i.cluster and i.maxlik manuals and also the following i.segment command:
i.segment group=lsat7_2002@w1-imagery output=lsat7_2002_segments threshold=0.5 goodness=lsat7_2002_segments_goodness (using the imagery group created in i.cluster example, otherwise unrelated) I looked at goodness from i.segment and then reject from i.maxlik. I noticed that there is some correlation between these two. Well, this is quite okay since they are using same pixel values. However, then I noticed that low values of goodness (-5000, ...) correlate with low values of reject (1 == 1%). But the i.maxlik manual says that "1 = keep and 16 = reject". Can somebody explain this to me and perhaps suggest improvement to the manual? Shouldn't high rejection correlate with low goodness? And also, less important thing, i.maxlik reject is an categorical map with percentages reclassified to 16 classes. Does this have some practical meaning or is this just an over-left from integer-only times? Thanks, Vaclav http://grass.osgeo.org/grass71/manuals/i.cluster.html http://grass.osgeo.org/grass71/manuals/i.maxlik.html http://grass.osgeo.org/grass71/manuals/i.segment.html
