The computation of optical flow
TL;DR: The computation of optical flow is investigated in this survey: widely known methods for estimating optical flow are classified and examined by scrutinizing the hypothesis and assumptions they use.

Digital image correlation using Newton-Raphson method of partial differential correction
TL;DR: In this paper, the authors developed and limited experimental verification of a method which can determine displacements and gradients using the Newton-Raphson method of partial corrections, which was shown to be accurate in determining displacement and certain gradients, while using significantly less CPU time than the current coarse-fine search method.
