A Study On Chinese Document Layout Analysis

The layout analysis is part of important pre-processing of character recognition. The accuracy of Layout analysis has direct effect on efficiency of character. We provide a Chinese layout analysis method base on fuzzy connectedness and recognition features for complex document layout. This is a process including the input document images ., skew correction and Texts/Graphics segmentation. The bottom-up approach used in Texts/Graphics segmentation. All the connected units in the page are detected by search algorithm of connected region. The row-column mergence of the character is defined by fuzzy connectedness of the connected units at four orientations. The combination of punctuation we adopt the method of combination behind recognition due to great effect of mergence. In order to reduce time overhead, the local searching strategy is used in the process of calculation and mergence. The result of experiment has shown that this method can analysis belter prinled-quality document with satisfactory segmentation.
