  3. Thus the areas of the overlapping regions are compensated efficiently and the accuracy of measurement is highly improved. the volume of the bubbles can be estimated on the bubbles " area information, and a genetic algorithm ( ga ) based method is used to match and track bubbles in the image sequences, which solve tracking problem under complex conditions efficiently, such as some bubbles may have kinetic occlusion and crossover, some newly generated bubbles may entered into flow field and run away. a smooth kinetic locus is obtained by fitting the discrete centroids with a cubic spline function and at the same time the visual measurement is realized

    根據氣泡在圖像平面中的面積估計氣泡的體積，並對流場中的所有氣泡採用遺傳演算法進行最佳的匹配跟蹤，有效地解決了氣泡群在流場中出現如遮擋、交又、新它『出現、逃逸等復雜情況下的準確跟蹤，並採用三次樣條插值方法對離散的質心點軌跡進行擬合，得到氣泡在流場中平滑的運動軌跡，從而實現了摻氣水流特性的可視化測童。
