In this paper a new feature called crosscount for document analysis is introduced.The feature crosscount is a function of white line segment with its start on the edgeof document images. It reflects not only the contour of image, but also the periodicity of white lines(background) and text lines in the document images. In complexprinted-page layouts, there are different blocks such as textual, graphical, tabular, andso on. of these blocks, textual ones have the most obvious periodicity with their homogeneou…
