face recognition challenge: how to run the benchmark

edit

it is here .

you will need to download the opencv_contrib repo, add it to your main opencv cmake, and rebuild ( to get the datasets module)

then compile the fr_lfw_benchmark.cpp program.

come back, if you run into problems.

There is a guide for this task: Run test with LFW database. See more at the sample code at the dataset module.
