Comparison, Analysis and Review of 2D Flow Visualization

Flow visualization is a very active subfield of scientific visualization, and the study of 2D flow visualization can afford foundation for 3D flow or higher dimensionality flow. There have been several classifications by different authors. The classifications were integrated into four types: direct flow visualization, texture-based flow visualization, geometric flow visualization and feature-based flow visualization, after consulting papers published in recent years, a new type of 2D flow visualization technique was added based on information theory, then several typical algorithms were introduced and compared. On this basis, charts and forms were used to state the results of comparison.
