Compute distances such as MSR, SNR and L2 on images
SNR uses CMake to generate Makefile or project (for Visual Studio or XCode). You can find CMake here. SNR also requires Boost library to be installed. You can find Boost here.
cmake .
make
SNR requires two EXR files to be specified: one reference file and the query file for which the metrics will be computed.
./SNR file.exr reference.exr
where file.exr is the query file and reference.exr is the reference image.
