Rotation Index-Based Vortex Extraction and High Quality Texture Advection for Surface Flow Field

Abstract:

Vortex detection for surface flow field is a challenging issue in feature visualization. This paper presents a new vortex detection technique for surface flow field based on rotation index. Rotation index is the statistical quantity of vectors around a point, and indicates the rotation character of the sample region around the point. Then, an ELIC-based IBFVS method is applied to visualize the result flow field. A discussion of results is included to demonstrate our algorithm which leads to a more reasonable visualization results.
