Boundary Deformation Measurement by Mesh-Based Digital Image Correlation Method
Applied Sciences, 2020 Digital image correlation (DIC) is a popular photomechanics method for deformation measurement. The conventional subset-based DIC method obtains the displacement vectors at the subset centers, but cannot calculate the deformation on the specimen edges ...

Rapid Measurement of Spectral Characteristics by Correlation Matching Method [PDF]
arXiv, 2015 In this paper, we have established the couple system of a spectroscope, CCD and computer and proposed a method of the rapid measurement on spectral characteristics such as central wavelengths, relative intensities, sensitivity lines and the wavelength range and image pixel of the spectral images of a material by using the correlation matching method ...

Focus Quality Assessment of High-Throughput Whole Slide Imaging in Digital Pathology [PDF]
arXiv, 2018 One of the challenges facing the adoption of digital pathology workflows for clinical use is the need for automated quality control. As the scanners sometimes determine focus inaccurately, the resultant image blur deteriorates the scanned slide to the point of being unusable.

On basis images for the digital image representation [PDF]
arXiv, 2019 Digital array orthogonal transformations that can be presented as a decomposition over basis items or basis images are considered. The orthogonal transform provides digital data scattering, a process of pixel energy redistributing, that is illustrated with the help of basis images.

Measuring Atmospheric Scattering from Digital Images of Urban Scenery using Temporal Polarization-Based Vision [PDF]
arXiv, 2014 Particulate Matter (PM) is a form of air pollution that visually degrades urban scenery and is hazardous to human health and the environment. Current monitoring devices are limited in measuring average PM over large areas. Quantifying the visual effects of haze in digital images of urban scenery and correlating these effects to PM levels is a vital ...

Digital Image Correlation for Performance Monitoring. [PDF]
, 2016 Evaluating the health of a mechanism requires more than just a binary evaluation of whether an operation was completed. It requires analyzing more comprehensive, full-field data. Health monitoring is a process of non-destructively identifying characteristics that indicate the fitness of an engineered component.
