| Outline of Final Research Achievements |
This research developed s extended morphological operations based on geodesic distance in image spaces. Our method computes morphological operation for local regions that is structurally near from the target pixels, and this enables to simplify local structure while preserving global structure of the object. In addition, we also developed approximate method with clustering in order to reduce computational cost. Semantic medial axis, rough skeleton structure of the objects can be computed for the simplified objects by medial axis transform methods.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で開発した測地線距離に基づくモルフォロジー操作及びそれに基づく中立軸変換技術は，微細な位相構造を取り除き、形状そのものが持つ 概形特徴に基づき中立軸を計算する.その結果現実世界に存在する物体をコンピュータ内により簡単な構造で取り込むことが可能となる。これにより、コンピュータ内での3次元計測データ処理が容易になるため、諸問題の解決に貢献する。
