基于数学形态学的版面分割

PAGE SEGMENTATION BASED ON MATHEMATICAL MORPHOLOGY

证明了由连通类C及膨胀运算δ可构造新的连通类Cδ,讨论了C与Cδ 的关系 .在引入极大连通子集的概念后给出了集合基于连通类的唯一分割 ,利用集合X基于Cδ 的分割与X的膨胀δ(X)基于C的分割之间的对应关系 。

It is proved that a new connectivity class C δ can be constructed by given a connectivity class C and a dilation operator δ . Using the concept of maximum connected subset of one set, the authors can obtain sole segmentation for one given set based on the connectivity class. After the corresponding relationship between the segmentation of X based on the connectivity class C δ and the segmentation of δ(X) based on the connectivity class C is introduced, the authors propose a new approach based on mathematical morphology for page segmentation.
