数学形态学提供了一种以形态或集合论为基础对图像进行分析理解的工具。可以用来去除噪声、抽取骨架、插补、分割、多分辨率分析、匹配等。 包括四个主要的算符：扩张（膨胀）○＋，腐蚀○－，开○，闭●- Mathematics morphology has provided one kind carries on the analysis understanding take the shape or the set theory as the foundation to the picture

应用数字图像处理技术对采集到的木材缺陷图像进行预处理，运用数学形态学腐蚀膨胀等运算填补缺陷中的空洞来提取缺陷目标图像(Using digital image processing technology to preprocess the collected wood defect images, use mathematical morphology corrosion expansion and other operations to fill holes in the defects to
