| 6. | The attempts using k - l transform to fit line and introducing a new expression of the ellipse parameters improve the robustness and decrease the complexities of the algorithms
在吸取有关文献的基础上采用k - l变换进行直线拟合，提高了拟合鲁棒性和精度。 |
| 7. | Then a fast computing method is presented to estimate the curvature of edge points and the points at which curvature is less than some threshold are collected to fit lines
为提取直线边缘，使用改进的序列细化算法将边缘细化为单像素宽，而后用一种快速曲率估计方法估算边缘点的曲率，并保留估算值很小（约等于零）的点拟合直线。 |
| 8. | If a higher accuracy resolution is required , the distances of points to the fitting line can be taken as the judgment standard , and the data eliminated noise points by hough transform can be simulated by the least square method
当精度要求较高时，可将各拟合点到拟合直线的距离作为判别标准，对经霍夫变换剔除干扰点（或噪声）后的数据点再进行最小二乘法拟合。 |
| 9. | 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
该方法先检测出名片的四条边缘拟合直线，由四条边缘拟合直线的倾斜角度来确定名片图像倾斜角度，然后采用逐段整块搬移的方法来对图像进行倾斜校正，再根据边缘拟合直线位置去除黑边。 |
