Yeah, a lot of these things that get wrapped up as super-futuristic innovations that use the hottest buzzwords are really just ways to apply old techniques more efficiently. Since phones provide a platform for a robust software camera, instead of requiring the user to manually snap 9 shots for HDR, the phone just does it for you in rapid succession. Some DSLRs will do this automatically too with 3 shots, but they are much worse at providing a space for robust software assistance. It sounds like obstruction removal is the same kind of thing, where the phone actually captures a snippet of video and automatically differences that for you, instead of having the photographer take multiple photos and difference them manually in Photoshop (as has been done for a long time, e.g. [0]). And since Google automatically uploads all of your content, they can analyze it on their servers and return an asynchronous result. They do this for auto-generated animations, panoramas, and movies; it doesn't all have to be performed on the local device and they can take their time. This is not to poo-poo such developments; I think it's awesome that I can use Cardboard Camera and get a stereoscopic 3D image of my surroundings. Even special-built 360 cameras like the Theta S struggle with stereoscopy. I would love to see Canon or other camera makers innovate by providing a DSLR platform that makes it easy to load new software macros that enable cooler shooting and processing modes (with the caveat that the DSLR must never allow these to slow the device's operation in no-macro mode). The best we can do now is a full-custom firmware like Magic Lantern [1], which is cool and all, but when I tried it on my 6D, the camera response time was much slower and the sound recording didn't work on the build I installed, resulting in a couple of home videos without audio. I took ML off and haven't been inclined to try again.
