The aim of this work is an experimental hydrodynamic analysis of two-phase gas--liquid flow carried in bubble column with the usage of digital image processing method (DIP) connected with statistical analysis. The measurement signals were recorded by high speed CMOS camera images sequences of the two phase flow. The results of the image processing and statistic analysis were flow regimes identification and velocity determination.
