A summary of research on image visualization in fluid flow is presented. The review
addresses the topics of method in image processing, the application of particle image velocimetry and
different sensor source of tomography. One of the greatest challenges in image visualization research
is the improvement of flow measurement for multiphase flow. As there a lot of prediction in studying
multiphase flow, the selection of image visualization method has to be chosen carefully. The important
part is the method to process the image which consists of parameters to be studied. The improvement
in image visualization method is important to further applied to other area of process.
