| 摘 要： | 为提高倾斜图像纠偏处理的正确率与运算效率,提出一种改进的Hough变换图像纠偏算法.该算法根据扫描文稿图像的特性,设定了边缘区域计算,并基于此约束下对倾角进一步限制,从而在无损内容的前提下,显著提高了倾斜角度计算效率.实验结果表明,对于普通文稿扫描图像该算法在保证准确率的前提下比标准Hough变换倾角运算效率提升约15倍.

| Abstract: | In order to improve the tilt image correction processing accuracy and computational efficiency,this paper proposes an improved Hough transform image correction algorithm.The algorithm is based on the scanned document image features,the edge of a straight line calculation is proposed,and based on the constraints on the inclination to further limit,ensuring the correct calculation,the effeicency angle is greatly imroved.The results show that,this algorithm is about 15 times if affer than the stamdard Hough transform operation. |
