Unfortunately Gwyddion still lacks working advanced segmentation filters. This kind of images should be first filtered (equalizing intensity over image, maybe stretch color scale to improve contrast, apply smoothing filter to remove small single pixel local noise), than right watershed or maxflow/mincut algorithm should work and probably right combination of local height more than threshold intersection with curvature less than threshold can also give decent result with smoothed enough surface. The current watershed implementations do something strange, watershed algorithm as it is described in documentation should work after some tuning of parameters, but it has some problems in implementation.
