From: Measuring acceleration fields via regularized digital image correlation
Displacement fields (in \(\upmu \)m) along x at \(t=85~\upmu \)s. a Reference solution, b instantaneous DIC, c spatiotemporal DIC, d dynamically regularized DIC (\(\ell _D=75\) pixels). All analyses lead to very low RMS differences between measured displacement fields and the reference solution. The dynamically regularized solution lowers the RMS difference by a factor of 2 in comparison with the other two analyses
