Abstract
The presence of salt-and-pepper noise in speckle image prevents the precise measurement of deformation and displacement fields in the traditional digital image correlation (DIC) technique. Spearman's rho (SR) has been introduced as a kernel correlation function in the DIC. The robustness of SR is quantitatively analyzed in following two cases: one is speckle images contaminated by same distribution salt-and-pepper noise, and the other is contaminated by random distribution noise. Theoretical and simulation results suggest that the DIC using SR is robust to about 10% salt-and-pepper noise. SR is suitable for measurement deformation and displacement fields.
