Using this description of space, the contours of printed regions arc identified with significant accuracy. the new approach is fast as there is no need for skew detection and correction in most conditions, and only few simple operations are performed on the description of the background ( not on the pixel - base data ). in addition to the page segmentation step, we also introduce a skew detection method based on two vertical lines
和同類方法比較，該方法具有許多的優點：它對于版面中非規則的復雜圖形的處理可以得到和對規則圖形處理一樣的效是；在模糊參數選取經驗值的情況下對于傾斜的版面同樣可以進行處理，並且不影響處理的效果；該方法還可以針對某一特定區域而非整個版面單獨使用。 -
