煤泥浮选泡沫图像分割与特征提取

Feature extraction based on image segmentation of coal flotation froth

针对在煤泥浮选泡沫图像中的煤泥气泡互相粘连、边界模糊的情况,根据分水岭变换模拟浸水原理,提出一种新的、有效的分割算法,同时应用数学形态学中的腐蚀和膨胀算法,解决了经典分水岭算法不能处理的过分割和欠分割问题,使得粘连的煤泥气泡得到了有效的分割.然后计算出各个煤泥气泡的横截面积、周长、形状等物理特征参数,这些参数是实现自动控制浮选过程的重要依据.

An efficient segmentation algorithm based on watershed transformation was put forward for the coal flotation froth in which the bubbles are connected and have the murky verge between them.The dilation and erosion operations based on mathematical morphology solved the problems of over segmentation and under segmentation of the connected components.This algorithm successfully segments the froth bubbles and gets their characteristics-the cross sectional area,girth,and shape of the bubbles which are important i...
