基于稀疏度差异的快速版面分割方法
Fast layout segmentation algorithm based on sparsity difference
摘要
Abstract
A fast page segmentation method based on the region sparsity difference was proposed to simplify the layout segmentation method and improve the efficiency of layout detection.The sparse degree was employed as the feature description of page regions.Then the threshold segmentation was applied to obtain the category labels according to the difference between contents and the back-grounds.Our approach was tested on a complex layout image set.The experimental results,accurate rate 74.1% and the computation time 1.61 seconds,show the effectiveness and rapidity of our meth-od.Comparing with the improved connectivity-based layout segmentation method,our method has simpler process,easier computation and better applicability.关键词
