The algorithm begins with pre-segmentation at a low resolution level and transmits the result to optimally segmentalize on a higher resolution scale. 在粗尺度上采用基于区域的高斯噪声模型分析图像，并和测地线模型相结合实现预分割，预分割结果表明了组合模型能自动和精确地提取边界。
The key problem to realize online particlesize analysis based on digital image processing technology is image segmentationand to segmentalize or get rid of the linking particles. 采用计算机图像处理技术进行在线粒度检测的关键问题是图像分割和粘连颗粒的分割和剔除。
