Deep DIC: Deep Learning-Based Digital Image Correlation for End-to-End Displacement and Strain Measurement. (arXiv:2110.13720v2 [eess.IV] UPDATED)

Digital image correlation (DIC) has become an industry standard to retrieve
accurate displacement and strain measurement in tensile testing and other
material characterization. Though traditional DIC offers a high precision
estimation of deformation for general tensile testing cases, the prediction
becomes unstable at large deformation or when the speckle patterns start to
tear. In addition, traditional DIC requires a long computation time and often
produces a low spatial resolution output affected by filtering and speckle
pattern quality. To address these …
