摘要
提出了一种新的算法用以提高名片识别系统中的图像倾斜校正效果。根据倾斜像素在相邻像素中所占的面积,进行面积插值,获得像素的灰度值。将这一算法应用于名片识别系统,利用从系统中获取的倾斜角度和顶点坐标,得到了很好的校正效果。
To prompt the effect of image rectify in the Chinese business card automatic recognition system, in the paper, a new algorithm is proposed, which makes use of the areas that the gradient pixel occupies to carry out the interpolation and to get the objective gray-level. Applying the algorithm to business card recognition system and using the skew angle and the border gained from the system, excellent corrected results will be obtained.
