【摘要】 形态滤波是基于图像的几何结构特性,利用预先定义的结构元素对信号进行匹配或局部修正,以达到提取信号,抑制噪声的目的。本文从研究形态滤波器的基本理论入手,通过形态变换的组合和柱状图均衡化操作,用M atlab实现了中药显微特征灰度图像的噪声滤波,得到了较好的结果。更多还原

【Abstract】 Morphological filter is based on the geometrical-structural features of images.In order to achieve the aims of collecting signals and suppressing noises,morphological filter is matched with or modifies locally the signals by the structuring elements defined in advance.Starting from the investigation of the fundamental theory of morphological filtering and the combinations of morphological transforms,the noise processing for Microscopic characteristics of Chinese herbal has been accomplished by Matlab.更多还原
