Fig. 1

Standard displacement (a) and acceleration (b) uncertainties for instantaneous and spatiotemporal analyses (\(\ell _t = 1\) ms). The physical size of one pixel is 200 \({\upmu }\)m. The dash-dotted lines show the estimates based on the inverse DIC Hessians. The standard compromise between measurement uncertainty and spatial resolution is illustrated for both kinematic quantities. The benefit of temporal regularization is substantial for accelerations, and more limited for displacements
