利用动态结构元素提取直线

Line Extraction Using Dynamically Structured Element

研究了灰度文档图像中提取直线的方法 首先将灰度文档图像利用半色调技术转换为二值图像 ,进行倾斜矫正后利用Hough变换动态构造结构元素 (HTSEC) ;然后根据这些结构元素 ,利用数学形态学中的击中 /击不中变换提取文档图像中的直线 (MMLE)

This paper studies line extraction from grayscale document images. First, the grayscale image is converted into binary image using halftone technology. After skew correction, Hough transform is used to construct the structured elements, which in turn are applied to the hit or miss operator for mathematical morphology-based line extraction(MMLE).
