  1. For bilateral symmetry objects, the techniques on symmetry - point detection and symmetry - axis extraction are presented based on harmonic conjugation relationship. for rotated symmetry objects, the techniques on rotated units description and rotated symmetry center extraction are presented based on center invariants of objects. further more, by using 3d invariants and 2d projective transformation, an approach to recover shape from part symmetry objects is realized on some conditions

    ( 3 )深入分析了2d對稱性目標透視成像的幾何特點,將共點四線交比用於目標輪廓上的關鍵點的特性描述中;利用調和共軛關系,提出了一種針對左右對稱型目標的對稱點檢測和對稱軸提取的演算法;利用交比關系構造了目標的形心不變量,提出了一種針對旋轉對稱型目標的旋轉對稱單元判定、旋轉中心提取的演算法;進一步利用3d不變量和2d射影變換,實現了一定條件下的對稱性目標的形狀恢復技術。
