V. CONCLUSION
This paper presents a water body extraction method
based on LEGION (NDWI). The experiment results
indicated that the proposed method could extract the
coherent water body with smooth and clear edge
accurately.
Because the oscillation network was dependent on the
feature function, it was important to construct an
appropriate feature function which can bind the object
tightly.
