Use of digital image correlation technique in full-scale testing of prestressed concrete structures
TLDR
The DIC technique could provide very accurate and detailed information, including the in-plane and out-of-plane strains and their spatial variations, and the locations of high tensile and compressive strains which at later stages of loading result in cracking or crushing of concrete.About:

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.

Systematic errors in digital image correlation caused by intensity interpolation
TL;DR: It is shown that the position-dependent bias in a numerical study can lead to apparent strains of the order of 40% of the actual strain level, and methods are presented to reduce this bias to acceptable levels.
