摘要 在文档影像的自动处理中,去黑边和去噪是影像文档预处理的首要环节。在去除黑边的处理中,运用了数学形态学的理论和方法去除黑边;在去噪的过程中,采用灰度增强和维纳滤波相结合的方法进行图像的去噪。大量的实验结果表明,文章所采用的方法可行。 In automatic document image processing, black margin removal and denoising are two principal steps. In removal black margin processing, using the method of Mathematical Morphology; we using the methods of image enhancement and Wiener Filtering remove noise. Lots of experimental results show that the method is feasible.
