Abstract
Image processing of flow visualization pictures is an effective technique to obtain full-field velocity information in a wide variety of fluid mechanics problems. This report describes the development of an image processing algorithm which employs automatic analysis of the flow visualization images to establish local, instantaneous velocity information. The automatic method utilizes gradient operators and curve fitting techniques to extract the valid flow streaks. It is demonstrated how this technique may be used to determine local velocity vectors for a variety of flow visualization images. The analysis is accurate and fast.
