摘要
针对数学形态学在工程图纸矢量化过程中去噪处理的缺点,通过研究形态学运算的特点,结合图像算术运算和模板滤波的技术,在基于数学形态学的混合去噪方法的基础上进行了改进和扩展。这种改进后的方法不仅可以保留细图线,而且可以还原图线间狭长间隙,达到既消除各种噪声又保持了图像的细节,具有良好的处理效果。
Aiming at the disadvantages of mathematical morphology used in the engineering drawing's veetorization, through analyzing the morphological operation's characters, the method of mixed de-noising based on mathematical morphology can be improved and expanded with the image's algorithm operation and template fihering. The improved method not only retains the thin line in the drawing image, but also recovers the narrow interspaees between lines, which can eliminate all sorts of noise and maintain the image's detail, and gets better effect.
