Conclusions

A new algorithm for fringe thinning is proposed which uses the concept of minimum intensity criterion to extract the fringe skeleton. Application of this algorithm using rowwise scanning for a circular disk under diametral compression to determine material fringe value has brought out the accuracy of the algorithm. The algorithm is simple and straightforward. A more generalized scanning, wherein the pixel having minimum intensity within the edges of the fringe is identified by taking into account the curvature of the fringe, is currently under development. Although only thinning of isochromatic fringes is described in this paper, with little modification the algorithm can be extended for processing isoclinic fringes, too.
