I use Go to process images for my food project. I specifically use a library with bindings to libvips

It runs on both osx and linux for me

There is also bindings for OpenCV here is one

Because maybe i'll write some complex function. With C++ and OpenCV,it's very faster and better. I extend use cgo for call c++ fuction. But i don't know speed of it.
