Abstract
In order to enforce the particle tracing capability, an idea of temporal continuity of motion is integrated into the BIC method. By assuming that particle floating in fluid will not change suddenly its motions within a short time, measured velocity vectors in two successive instances are connected and examined their validity. The new method is applied to sequential pictures of a visualized flow, and result are found to be quite satisfactory. By integrating the idea into the BIC analysis, measured particle trajectories become more reliable without losing its efficient analysis.
