Facebook open-sources A.I. software for segmenting objects in images

Facebook today is announcing that it's open-sourcing some of its latest artificial intelligence (A.I.) software for segmenting objects within images. The DeepMask, SharpMask, and MultiPathNet tools are available now on GitHub under a BSD license. It's not as if Facebook is opening up about these programs for the first time. They've been described in academic papers (specifically this one, this one, and this one). Now Facebook's Artificial Intelligence Research (FAIR) lab is connecting the dots with an extensive blog post and is also, of course, making the software available free for others to inspect and build on.
