A Chinese document layout analysis method based on minimal spanning tree clustering
Xuedong Tian, Chong Zhang · 2004
For adapting to some special characteristics of Chinese documents, a method based on minimal spanning tree clustering is presented. This method is a bottom-up approach. First apply run-length smoothing algorithm on the document in horizontal direction, and then in vertical direction. After that, minimal spanning tree clustering is applied. We can infer from experiments that the problem of Chinese document layout analysis can be resolved in a better way.
