Autofocus is an extension for the Focus plugin.
Basically, it acts as a JS image.upload / image.replace hook, processing the / each image with the focus component, determining its appropriate focus point and saving it to the meta data file.
It is intended as a fallback for the focus plugin, whenever the user doesn’t specify a focus point himself.
Well, ok, I’m choosing examples that work especially well 
It actually has ups and downs depending on the image, in short this is a pretty experimental plugin so be sure to test it carefully before using it. There are a few tests in the repo.
