Building

Dependencies

psnr_hvsm has several dependencies:

• FFTW3 >= 3.3.9
• pybind11
• xtensor
• xtensor-fftw
• xtensor-python

All of the above can be automatically resolved by running deps.ps1, which is a cross-platform PowerShell script (i.e. it can also be run under Linux if you have PowerShell installed).
