Gradient Correlation Functions in Digital Image Correlation [PDF]

open access: yesApplied Sciences, 2019
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

Reconstruction of Cylindrical Surfaces Using Digital Image Correlation [PDF]

open access: yesSensors, 2018
A technique for the reconstruction of cylindrical surfaces using optical images with an extension of least squares matching is presented. This technique is based on stereo-image acquisition of a cylindrical object, and it involves displacing the camera ...

Variation of mechanical properties in a multi-pass weld measured using digital image correlation [PDF]

open access: yes, 2009
As part of a programme investigating the structural integrity of welds, the Digital Image Correlation (DIC)technique was used to obtain the full-field strain distribution during tensile testing of cross-weld specimens cutfrom a multi-pass girth welded

Optimal digital color image correlation

open access: yesOptics and Lasers in Engineering, 2020
Abstract Within the context of Digital Image Correlation (DIC), the optimal treatment of color images is considered. The mathematical bses of a weighted 3-field image correlation are first introduced, which are relevant for RGB encoded images. In this framework, noise characterization methods are developed as noise properties dictate the best suited ...

Digital Image Correlation

open access: yesMaterials Today, 2010
Digital image correlation (DIC) is a classic pattern recognition technique that is widely used for experimental measurements, mainly for: (1) surface displacement analysis in solid mechanics, and (2) particle image velocimetry (PIV) in fluid mechanics. DIC is based on using a correlation function to locate the best matching position of two images thus ...

Mechanics-aided digital image correlation [PDF]

open access: yesThe Journal of Strain Analysis for Engineering Design, 2013
By construction, digital image correlation is an ill-posed problem. To circumvent this difficulty, regularization is often performed implicitly through the kinematic basis chosen to express the sought displacement fields. Conversely, a priori information on the mechanical behavior of the studied material is often available.

On the Digital Image Correlation Technique

open access: yesMaterials Today: Proceedings, 2022
Abstract This study has been focused in the introduction of the theoretical and practical foundations of the Digital Image Correlation DIC technique to undergraduate students at EPN through the implementation of a Laboratory DIC practice. In the experimental test, an elastomer with different hole shapes is used as a test specimen, which should have a
