基于文字特征和边缘特征的文本碎纸片拼接

Stitching of scrapped paper based on character features and edge features

针对手撕无规则的文本碎纸片拼接复原,分析了碎纸片的基本特征,提出了基于文字特征和边缘特征的拼接方法。先对碎纸片图像进行预处理,再对图像的文字特征和边缘特征进行提取。利用边缘特征,使用角点匹配算法拼接边界碎纸片,利用文字特征完成整个碎纸片的拼接。

For the hand-cut irregular pieces of paper scraping pieces of recovery, the basic characteristics of shredding paper was analyzed and this paper puts forward the splicing method based on character features and edge features. Firstly, the shredded image is preprocessed, and then the characters and edge features of the image are extracted. The corner matching algorithm was used to splice the boundary shredding sheet by using the edge features,and the whole splicing was accomplished by using the character feature.
