An Improved Hough Transform Image Correction Algorithm
Hongbo Song · Journal of Shenyang Ligong University · 2012
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.
