There are different considerations for the algorithm itself on the one 
hand, and an implementation of it on the other. The former may be 
covered by patents, the latter by copyright.

However, I see on the above link that there are multiple (at least 
three) Free (as in Software) implementation of A-KAZE, so I expect there 
to be no problem.

How did you expect to use the code ? Incorporate it directly (by 
cloning) ? Or referring to it as a third-party library user would have 
to install first ?

I think it would be great if users could switch between different 
implementations. In fact, it might even be interesting to establish a 
common API, then provide wrappers for the three above, and use 
benchmarking to measure how their performance compares. Or perhaps 
that's too ambitious and we need to restrict ourselves to one 
implementation.
