A data schema , especially a data subschema in a relational data system 關系數(shù)據(jù)系統(tǒng)中的數(shù)據(jù)模式,特別是子模式。
In feature matching , a dot pattern matching method is developed , which combine subschema matching method for solving rotations and scale changes problems , and employ variable bounding box to solve translations problem . then the problems of arbitrary translations , rotations , and scale changes in feature matching have been well 特征匹配算法采用了基于點模式的匹配方法,并結合基于結構的匹配方法解決圖像的旋轉、平移問題,同時采用可變限界盒方法解決圖像的變形問題,使得指紋圖像匹配中因圖像旋轉、平移、形變等帶來的問題得到了較好的解決。
