The plugin is part of a delineation tool, in which the output from gPb contour
detection and SLIC superpixels are combined based on random forest
classification. The subsequent interactive delineation is managed with the
BoundaryDelineation plugin.
In comparison to the initial version, the least-cost path now does not only
consider the segments lengths', but cost values per segment generated by the
random forest classification. Also the line simplification is modified, next to
minor edits in the code and on the GUI.
