fig. 5 - 8 Microdensograms and rel. frequency distribution - band 5 of an old mixed 
deciduous stand (fig. 5), an old mixed forest stand (fig. 6) a middle aged mixed- 
deciduous / Pinus silvestris stand (fig. 7), and a middleaged mixed-deciduous stand. 
The problems and (possible) successes in separating the different 
forest types are summarized in the cluster analysis illustrated 
in figure 9 and 10. These clusters are based on analysis carried 
out with statistical significance of 70% By using higher levels 
of significance the clusters become bigger and more overlapping. 
The software for this analysis has been developed bv G.Lange 
as part of the FIPS (Freiburger Image Processing System).
