Accurate displacement measurement via a self-adaptive digital image correlation method based on a weighted ZNSSD criterion

Digital image correlation (DIC) technique has been increasingly employed to implement surface deformation measurements in many engineering fields. Practically, it has been demonstrated that the choice of subset sizes exerts a strong influence on measurement results of DIC, especially when there exis...
