| Zusammenfassung: | A quantitative full-field velocity measurement technique involving imaging of displaced particles in a fluid is described. In this paper a fully automatic image processing procedure is developed to extract velocity vectors from flow visualization images. Flow visualization images are generated using special illumination coding which allows determination of both velocity magnitude and direction. The utility of this technique for detecting well-defined flow structures in a flow is demonstrated. |
