A Segmentation Method of PIV Images of Wind-sand Two-phase Flow based on MATLAB Platform
基于MATLAB图像处理算法的风沙两相流PIV图像的分割方法

In order to deeply understand the mechanical mechanism of sand particles movement,it is fundamental to acquire both instantaneous sand particles velocity and instantaneous airflow velocity simultaneously during wind tunnel test.This paper developed a segmentation method of two-phase flow PIV images based on MATLAB platform.The fundamental principle of this method lies in distinguishing sand particles from airflow tracing particles by particles' sizes of two-phase flow PIV images.This method can clearly segm...
