Some experimental observations of crack-tip mechanics with displacement data
Fracture and Structural Integrity, 2015 In the past two decades, crack-tip mechanics has been increasingly studied with full-field techniques. Within these techniques, Digital Image Correlation (DIC) has been most widely used due to its many advantages, to extract important crack-tip ...

Pixel-level robust digital image correlation
Optics Express, 2013 Digital Image Correlation (DIC) is a well-established non-contact optical metrology method. It employs digital image analysis to extract the full-field displacements and strains that occur in objects subjected to external stresses. Despite recent DIC progress, many problematic areas which greatly affect accuracy and that can seldomly be avoided ...

Spatial Variation of the Correlated Color Temperature of Lightning Channel [PDF]
arXiv, 2014 In present work, we propose the analysis method of lightning based on the color analysis. We analyzed the digital still images in which the cloud-to-ground (CG) and intracloud (IC) lightning flashes are shown. Applying some digital image processing techniques, we extracted lightning channels.

Incoherent digital holograms acquired by interferenceless coded aperture correlation holography system without refractive lenses [PDF]
arXiv, 2017 We present a lensless, interferenceless incoherent digital holography technique based on the principle of coded aperture correlation holography. The acquired digital hologram by this technique contains a three-dimensional image of some observed scene.

Adaptive Subset-Based Digital Image Correlation for Fatigue Crack Evaluation
Applied Sciences, 2020 This paper proposes a fatigue crack evaluation technique based on digital image correlation (DIC) with statistically optimized adaptive subsets. In conventional DIC analysis, a uniform subset size is typically utilized throughout the entire region of ...
