摘要
提出一种基于图像处理的打印机自动文件提取算法。通过对经过边缘检测的文件图片进行Hough变换,检测满足条件的直线组合,从而定位出文件在图片中的区域,又通过文件顶点的坐标确定出文件的长宽比,再通过校正从而得出一个矩形的文件图。实验取得了很好的效果。
In this paper, we present an algorithm based on image processing for multi-function print to automatically extract the documents. First, by performing Hough transform on the document picture with edge detection, the condition-satisfied straight line combination is detected so as to locate the region of the document in picture, then the aspect ratio of the document is determined according to the coordinates of docu- ment' s vertex, and finally, a rectangular document graphics is obtained through rectification. Good results were attained in the experiments.
