基于模糊距离变换的颗粒图像分割方法

在颗粒图像中,经常存在颗粒重叠或者粘连现象。本文提出了一种新的图像分割方法。该方法首先对颗粒图像进行二值化,然后对图像作模糊距离变换得到模糊距离图,再利用分水岭算法将粘连或者部分重叠颗粒分离。实验证明,此法能够将粘连颗粒物图像有效分离。

The Separating Algorithm for Overlapping Grain Images Based on Fuzzy Distance Transformation

In actual grain image,there always have the conglutinant or overlapping phenomenon.According to this situation,a new algo-rithm used to separate the overlapping grain is introduced.This method is that we first threshold image from the image,then we apply Fuzzy Distance Transform to get fuzzy distance image,and finally,we use the Watershed algorithm to apart conglutinant or overlapped grain.The result of the experiment shows that this method has high performance on conglutinant grain segmentation,and this method is al-so applicable for separation of all kinds of overlapping granule images.
