Gradient Correlation Functions in Digital Image Correlation [PDF]
The performance of seven different correlation functions applied in Digital Image Correlation has been investigated using simulated and experimentally acquired laser speckle patterns. The correlation functions were constructed as combinations of the pure

Stereo digital image correlation: formulations and perspectives [PDF]
A literature review regarding functionals used in stereo digital image correlation (SDIC) is presented. A suitable functional for performing data assimilation, in the sense that all available information at all times is wisely taken into account, is also

In-plane strain measurement by digital image correlation [PDF]
This paper presents a "fast and simple" (FAS) detection algorithm based on the digital image correlation for measurement of the surface deformation of planar objects. The proposed algorithm uses only fine search at the pixel level resolution and surface fitting for sub-pixel level.

CONTROLLING TESTING MACHINES WITH DIGITAL IMAGE CORRELATION [PDF]
It is proposed to discuss a strategy to control a mechanical test by using digital image correlation. A two-loop system is developed to integrate a sub-pixel correlation algorithm to evaluate the average strain of a region of interest and control a servo-hydraulic testing machine.

Study of image characteristics on digital image correlation error assessment [PDF]
In this paper, errors related to digital image correlation (DIC) technique applied to measurements of displacements are estimated. This work is based on the generation of synthetic images representative of real speckle patterns. With these images, various parameters are treated in order to determine their impact on the measurement error.

DuoDIC: 3D Digital Image Correlation in MATLAB
Three-dimensional Digital Image Correlation (3D-DIC) is a non-contact optical-numerical technique for measuring the 3D shape and full-field displacement, deformation, and strain, from stereo digital images of the surface of an object. 3D-DIC is useful in
