Good in-body NR algorithms: how difficult is it?

We all know Canon sets their in-camera NR to very strong settings, smearing quite a bit of detail. Even when it is turned off completely, there is some smearing going on.
On the other hand, latest bodies are real computer powerhouses: the 5D3 can even do in-body HDR and blending modes!
How difficult is it for Canon to implement REALLY good noise reduction as we see in third party produtcs that can actually reduce noise AND preserve fine detail?

I am always quite surprised by the results I get from Noise Ninja, Topaz and Nik products. I wonder how much better it could be if I didn't have a smeared image to start with...


Photography is about GEAR and not talent or practice. Practice won't make you a better photographer. Expensive equipment will. =D

Would be nice if Magic Lantern let you do this.

I may be behind the times, but in my experience the only good noise reduction occurs when a mask is applied to protect details, and when the NR being is applied is tailored to the specific image and the specific type of noise.

With that in mind, I can not foresee a way to have in camera NR that is even remotely as effective as the methods I would suggest people use in software.

This is just one of the many reasons I shoot RAW.

Any PP you apply on the computer has the benefit of a higher level CPU and better RAM, etc. Also, you can turn NR off in camera to avoid smeared files or shoot RAW.
What I'd like is Canon to apply Noise Ninja kind of algorithms in their Digital Solutions Software.
