| 摘 要： | 提出了一种基于连通域的文本图像倾斜校正方法.使用基于连通域的分行算法对倾斜文本图像的文本行进行分行,用线性回归公式计算出每一个有效文本行的拟合直线和倾斜角,根据有效文本行的加权平均倾斜角度,对倾斜文本图像进行校正.实验结果表明该方法是有效的.

| Abstract: | A method for skew correction of document image based on connected components was proposed.The skew document image was grouped into line segments by using connected components algorithm,and the fitting line and skew angle of each valid line was calculated through linear regression analysis formula,then correction of the skew document image were operated according to weighted average skew angles.The experimental result shows that the new correction method is efficient. |
