Demosaicing and noise reduction in leading commercial products

Where can I find information about the technologies behind the demoisaicing and noise reduction/removal modules in products such as LR, Capture One, Topaz etc.?

I am especially interested in combinations of demosaicing and noise reduction because these problems are closely related, and, it would seem, would be best solved in tandem. In both cases one is estimating the intensity/color of a pixel based on incomplete/noisy information about the pixel itself and the neighboring pixels, under the assumption that the intensity and color are related to those of the neighboring pixels.

I found a couple of papers (Buades, Coll, Morel, Sbert (2007 and 2008), Keigo Hiragawa (2008, "Color Filter Array Analysis..."), the PhD thesis of Daniele Menon (2009), Paliy, Foi, Bilcu, Katkovnik (2008)), but I have no idea whether they are at all related to the commercial offerings.

Any information would be of interest.
