e Noise-like features (small islands off the coast) with less than 100 pixel size or 0.25 km" are segmented out. 
The final DEM shows significant improvement over the DEM generated by commercial softwares, PCI and Intergraph.

Fig. 6 Comparison of DEMs automatically generated by 
(a) this work (b) PCI OrthoEngine and (c) Intergraph 
ImageStation. The DEM covers 60 km x 60 km in 
BoRyung/BuYeo region, S. Korea. Originals in color. 
Color codes are specific within each image. The coast is 
on the lower-righthand side. Peaks in (b) and (c) are » 
300 m.
