Newspaper layout analysis incorporating connected component separation

摘要

This paper presents an algorithm that performs automated segmentation and classification of newspaper images. A notable feature of the algorithm is a technique for segmenting components that are connected to other components. In particular, horizontal lines and vertical lines, which can be vital in determining the page layout, can be segmented from other lines and other components. The algorithm uses a bottom-up approach to initially segment the image, classify patterns and extract text lines. The classified patterns are then merged into complete regions. The algorithm is tested on a set of complex English and Greek newspaper images dating back to 1900.
