The extraction of fringe curves is the foundation of the automatic quantitative analysis of interferometric Images. This paper proposes an efficient method for interferometric fringe curves extracting. First, alt fringe curve points are detected. Then these fringe curve points are tracked. Finaly, the fringe curves are extracted by a linking algorithm. The detection principal of the fringe curve points and criterions for curve point tracking and Interrupted gaps linking are discussed In detail. In the paper. The experimental results show that the method is effective.
