双面碎片的英文文件复原方法研究

Study on the recovery method of double pieces english file with two-sided fragment

对英文材料的双面规则碎片文件复原问题进行了研究.由于碎片边界是规则的几何形状,无法采用几何形状匹配算法进行复原,为此提出了基于碎片边缘像素特征的匹配复原算法,建立了双面二维灰度匹配数学模型.通过加入行约束条件,减少横向匹配中的纵向误差,并通过消除列匹配中的误差,优化了匹配算法.该模型可以实现块状双面英文碎片的完整复原.

The recovery method of english materials with double-sided regular fragments is studied. Geometrical recovery method is not suitable to these fragmented files due to their regular geometric boundary. This paper puts forward a matching restoration algorithm based on the characteristics of fragments pixels, and adds constraints to reduce the lengitudinal matching errors in the horizontal matching. Thus we establish a two-dimensinal pixed matchine mathematical model. Meanwhile, by eliminating the vertical errors , we optimize the matching algorithm. The model can be used in recovery of the double-sided regular fragments.
