This is pretty hard to say how the two documents are related. The patent's filing date predates the cited paper so the paper can not be considered prior art (although it is certainly possible there is other relevant prior art). It is possible the authors of the paper are familiar with the work of the inventors and vice versa. I haven't spent any time reading the two documents so I can't say how similar the techniques described in them are. It is very common to find different research groups working on similar projects.
