The boundary of land and water in a remote sensing image is defined as water front. Picking up the water front plays an important role in comprehensive management of waterline, strengthening of the ability in resisting nature disaster, and the research of waterline's environmental change. Using RS methods to pick up water front has advantages of wide-range, high-precision, and ability of dynamic monitoring...
