【摘要】 形态学重建滤波器是基于数学形态学理论提出的一类滤波器,它最大的优点是能够在滤波的同时,很好的保持图像的轮廓。在本文中,我们在阐述形态学重建滤波器基本概念的基础上,给出了重建滤波器在灰度图像简化滤波中的应用。通过使用交变序列重建滤波器,小于结构元素的明亮或者黑暗平坦区域被合并到了周围的区域中,为下一步进行标识提取提供了良好的简化图像。更多还原

【Abstract】 Morphological filter by reconstruction is a class of filters based on mathematical morphology.The most important feature of them is that they can filter image while well preserving contour information.In this paper,we introduce the basic concept of morphological filter by reconstruction.Based on this,,we apply alternating sequential filter by reconstruction to gray-scale image segmentation.We use it as image simplification filter and it remove the bright and dark flat zones that are smaller than the structuring element.It provided a good simplified image for marker extraction.更多还原
