> Safari and IE do not allow the access to the camera yet, neither on desktop, nor on mobile. You can check caniuse for updates.

I assume this could be solved by wrapping the JS library in something like PhoneGap and installing it as a native app?

That's correct. Phonegap/Cordova gets you access to the camera, and would provide the ability to capture an image for local-processing with this library.
