Measuring acceleration fields via regularized digital image correlation

Advanced Modeling and Simulation in Engineering Sciences, 2020
Digital image correlation (DIC) is a full-field measurement technique. In instantaneous approaches (i.e., registering two images), DIC only gives access to displacement (or velocity) fields.

Digital Image Correlation Characterization of Deformation Behavior and Cracking of Porous Segmented Alumina under Uniaxial Compression

Ceramics, 2023
In this study, the two-dimensional digital image correlation (DIC) technique has been applied to sequences of images taken from the surfaces of porous, segmented alumina samples during uniaxial compression tests.

Application of Digital Image Correlation to Cement Paste [PDF]

The 18th International Conference on Experimental Mechanics, 2018
In this paper digital image correlation (DIC) has been applied to study the deformation process of cementitious material at very early age. After mixing of cement-based materials, the cement hydration process begins. Consequently, the ongoing chemical reactions result in a 3D deformation process (shrinkage).

EVALUATION OF CORRELATIONAL INFORMATION IN DIGITIZED CELL IMAGES [PDF]

Journal of Histochemistry & Cytochemistry, 1974
The processing of digitized cell images by computer may yield information not only about a set of cell image properties but also about their mutual dependencies. Observation of the covariance matrix of image properties of cellular material showing a response to chemotherapeutic treatment, ionizing radiation or antigenic challenge or following a ...

Optimized Patterns for Digital Image Correlation [PDF]

, 2012
This work presents theoretical background on a novel class of strain sensor patterns. A combination of morphological image processing and Fourier analysis is used to characterize gray-scale images, according to specific criteria, and to synthesize patterns that score particularly well on these criteria.
