A new algorithm for fringe-pattern processing is proposed. It consists of tracing fringes along the fringe direction by searching the local extreme values of brightness distribution in the image. A detailed explanation of this method is given, the parameters and criteria for computerized processing are discussed, and some experimental results for testing the method are presented.
