Abstract: Layout segmentation is an important part of layout analysis. An improved page segmentation algorithm based on connective region which can effectively and quickly split the more complex images is presented, which is effective in reducing segmentation errors in the threshold of the original algorithm. The regions of the single text font have been expanded in the text image, so that the follow-up statistics in the distance between the connected regions is more accurate and convenient. The larger connected regions are formed by smearing the image through the statistic in the distance between the connected regions, and the regions of the text image are segmented. Experimental results show that the method is accurate, efficient and applicable, and it is superior for the more complex layouts segmentation.
