Digital image correlation (DIC) and optical flow (OF) toolkit 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).
