Feature tracking on an object which stands out clearly against the background? Using morphing filters on the segmented object? Not that innovative.
Now I do like the particle trick. You see this in some video games to highlight objects of interest (e.g. World of Warcraft). It makes it much easier for players to locate them and zero in on them against background clutter. Probably useful for AR if you have a good application case.
However, the potential is heavily constrained until you get displays capable of "non-interfering annotation" - which is to say, you need a good HMD and not a phone. Not that you can go out and buy "a good HMD" by this measure, but that's a big thorny mess out to the side of the software concerns.
