In this paper, we derive a technique for the measurement of the solid particle phase in a solid-liquid two-phase flow. The proposed method consists of a two-step algorithm for the localization of particles. In the first step, we devise a Normal-line Hough Transform method (NHT) and utilize it to detect the centre of the particles in the stereo images. In the second step, we validate the existence of the particle position extracted using NHT by comparing with a labeling parameter space that yield using image labeling technique, and this improves the robustness to noise and the precision remarkably. The proposed method provides a high detection rate with particularly low level of false positives, and an evident amelioration in time-consuming as well. We also present extensive experimental results to illustrate the efficiency of the proposed approach. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR] |
