Reliability-guided digital image correlation for image deformation measurement
Applied Optics, 2009A universally applicable reliability-guided digital image correlation (DIC) method is proposed for reliable image deformation measurement. The zero-mean normalized cross correlation (ZNCC) coefficient is used to identify the reliability of the point computed.

Digital Image Correlation (DIC)
2021Digital image correlation (DIC) is a full-field non-contacting optical method that can capture the shape, motion, and deformation of solid objects. The basis of the method is the matching of the gray values of points from an image of the surface of an object before and after deformation.

In order to detect the occurrence of failure in a material, visual observation is a very intuitive approach. Although global failure is many times easier to observe visually, more dedicated analysis is required to detect small changes indicating the occurrence of first failure.

High-speed digital-image correlation method
Optics Letters, 2009Provided that the software and hardware equipment in a digital-image correlation method is unchanged, the only major factor affecting integer-pixel correlation computation precision and the integer-pixel processing time is the size of the computing window.

Application of digital image correlation method to biogel
Polymer Engineering & Science, 2010AbstractThis study adopts the digital image correlation (DIC) method to measure the mechanical properties under tension in agarose gels. A second polynomial stress–strain equation based on a pore model is proposed in this work. It shows excellent agreement with experimental data and was verified by finite element simulation.

Self-adaptive Isogeometric Global Digital Image Correlation and Digital Height Correlation
2016This work explores the full potential of isogeometric shape functions for global digital image correlation. To this end, a novel DIC and DHC (digital height correlation) methodology have been developed based on adaptive refinement of isogeometric shape functions.

Global and local coordinates in digital image correlation
Applied Optics, 2007Digital image correlation (DIC) is commonly used to measure specimen displacements by correlating an image of a specimen in an undeformed or reference configuration and a second image under load. To establish the correlation between the images, numerical techniques are used to locate an initially square image subset in a reference image.
