skew lines 中文意思是什麼
skew lines
解釋
偏斜線-
First, this method decide the skew angle of a business card image according to four border fitting lines of the business card, then a method based on block move is provided to correct image and black border is erased based on position of border near - line
該方法先檢測出名片的四條邊緣擬合直線，由四條邊緣擬合直線的傾斜角度來確定名片圖像傾斜角度，然後採用逐段整塊搬移的方法來對圖像進行傾斜校正，再根據邊緣擬合直線位置去除黑邊。 -
The algorithm included three steps : firstly, the text sub - region was selected adaptively according to the feature that the edges contained in text regions was stronger than those in non - text regions ; secondly, the blank bars between two text lines were extracted by blank blocks searching ; thirdly, the skew angle of blank bar was calculated by directional fitting, and this skew angle was just the document skew angle
該方法首先通過對梯度圖像的統計分析，自適應地選取到了包含文字的特徵子區；在特徵子區內，論文把文字行間的空白條帶看作一條隱含的線，用優化理論計算出空白條帶的傾斜角度，這也就是文本的傾斜角度。 -
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。
