no problem, many thank for your reply!

OK, thanks, I will check this.

I was using Views.subsample in my old code (all I needed was an integer 
subsampling), but was going to "rather low level" probably way too 
early. Thanks for the hint.

For the moment, I just took the algorithm and reimplemented it in 
ImageJ1 - I am much more familiar there and really needed to get the job 
done.

I will try to play with OPS and definitely, I will keep eye on its 
development  - it really looks great and evolves pretty quickly.

This will for sure be interesting to follow!

Thanks again,
