Abstract:
In a technology for detecting the water level of a river by image processing, after an angle of view setting process, an area setting unit sets an arbitrarily defined certain range from the center of the set angle of view as a processing area. Then, a flow processing unit calculates, from the processing area, motion information and a flow direction, computes a flow density, determines a region having a high density and similar flow directions to be a flow of water currents, and deletes flows in the other directions. Thereafter, a graph-cut processing unit creates an object seed and a background seed for graph-cutting, and detects a water surface by automatic graph-cutting. After an edge extraction processing unit has performed edge extraction, a water level calculation processing unit determines an edge that satisfies a predetermined condition to be a water level line, and outputs a water level measurement result.

Claim (Index 6):
The water level measurement method of  claim 5 , wherein in the flow processing step, a water current flow is extracted from the motion information, and\n in the graph cut processing step, the water surface region is extracted by performing labeling processing on the extracted water level flow and the other flows based on the graph cut theory.
