Text Extraction from Gray Scale Document Images Using Edge Information

  title={Text Extraction from Gray Scale Document Images Using Edge Information},
  author={Qingqing Yuan and Chew Lim Tan},
In this paper we present a well designed method that makes use of edge information to extract textual blocks from gray scale document images. It aims at detecting textual regions on heavy noise infected newspaper images and separate them from graphical regions. The algorithm traces the feature points in different entities and then groups those edge points of textual regions. From using the technology of line approximation and layout categorization, it can successfully retrieve directional… CONTINUE READING
