Fast Checkerboard Demodulation (FCD) for Synthetic Schlieren imaging
For all functions to work properly the scripts in sub-directory ./general should be on your MATLAB path. Usage examples are found in the ./examples sub-directory. Type
help functionname on the MATLAB prompt for function specific usage info (or see the comments inside the function file).
Information on the FCD technique and the employed algorithms can be found in: Wildeman S., Real-time quantitative Schlieren imaging by fast Fourier demodulation of a checkered backdrop, Exp. Fluids (2018) 59: 97, https://doi.org/10.1007/s00348-018-2553-9, or https://arxiv.org/abs/1712.05679 (preprint)
