摘 要
游程平滑是版面分割前期常用的一种方法,它将具有较小距离的象素连通在一起形成连通元素。对这些连通元素加以分类是有效划分文本、图象和图形的前提。本文提出了利用几何特征的分类规则以及进一步细分的线结构特征检测方法。

Classification of Connected Documents Gotten by Run-length Smearing in Document Segmentation

()

Abstract
Run length smearing is often used in document segmentation. The most important thing after run length smearing is to classify the connected components to text, image or graphics. One rule using geometrical feature to classify the components is presented here. A method used to detect line structure in a binary image is also given out in this paper.
