| 摘 要： | 针对水中气泡图像的特点,设计了由反色,低通滤波和降低图像灰度级构成的预处理方法,使用基于形态学理论的分水岭算法对气泡图像进行分割,较好地从掺气水流图像中提取出了气泡。与常用的全局阈值法相比较,本研究方法具有精度高,能自动分割粘连气泡的优点。

| Abstract: | Considering optical characteristics of the bubble in water,an integrated image preprocessing method based on reverse brightness color,low-pass filter and reducing the grayscale resolution are proposed,and then,using a watershed algorithm based on Morphology theory on bubble image segmentation is used to extract the bubble better from the aerated flow image.Compared with the conventional contrast-based segmentation techniques in using a single global threshold,the watershed algorithm has the advantage of hig... |
