A number of other image correlation codes exist (this is by far not an exhaustive list):

- CMV and CMV\_3D: Developed at Laboratoire Navier [@bornert2004mesure], local and non-rigid code allowing discrete DVC used in @hall2010discrete

- Correlli: Developed by LMT Cachan, shared with colleagues but not open source [@hild2008correliq4]. Contains a cutting edge integrated DVC global approach

- FIDVC and qDIC: Open source code 2D running on Matlab [@bar2014fast, @Landauer2018] from The Franck Lab which is suitable for measuring large transformations

- TomoWarp2: Developed by some of the co-authors [@tudisco2017tomowarp2]. This software has a graphical interface for facilitating correlation but is technically limited to displacements/rotations, and has a slow line-search in rotation space

- muDIC: Pure Python toolkit, limited to 2D images [@muDIC] but has a fully function global approach

- UFreckles: Graphical Matlab code [@ufreckles] working on 2D, surface and 3D images with a global approach

- StrainMaster: Closed-source software for surface and 3D image correlation from LaVision

- VIC3D: High-speed closed-source software for surface imaging from Correlated Solutions
