Hi Julien,

I can't say for the recursive gaussian filters, but the reconstruction  
filters need to process the whole input to produce a valid result.
I'm afraid there is no way to stream this kind of filter and have it  
produce the exact same result as the non streamed one.

You may want to look at filters working on neighborhood instead of  
regions (regions can cover most of the image) for this kind of feature.

Regards,

Gaëtan
