here's my question - why isnt there a computational photography app startup that works on these phones (either android or iphone). Let's take android - the snapdragon 855 is a very standard flagship CPU and is on tons of phones (including the 450$ Xiaomi K20 Pro). Why isnt there a computational photography app that works on these phones ? Why is Pixel 4 - which uses the same 855 chip - the only one that has this software. Is it patent encumbered ? or is there some massive dataset deep learning stuff involved. I'm surprised that there isnt a startup that is building these apps out there.

Keep in mind this is a breezy review / mashup of things that are commercially viable, commercially presumed (already built into everything), and academic curiosity, without much distinction between the categories. Fun read, but don't extrapolate too much from this article.

What do you mean? There is a whole category of apps out there: https://play.google.com/store/search?q=face%20swap&c=apps https://play.google.com/store/search?q=face%20swap&c=apps

Issue may be that the algorithms are trained on specific camera unit and gathering a large database of data from all possible cameras may be difficult even for big guy like google. Google puts a ton of work into their camera app and you can get clones that work on other devices with varying degree off success. For example I have mi5s that uses the same sensor as first pixel and get quite decent results with arnova's gcam clone.

  I'm not referring to GCam clone. I'm asking can't someone build this commercially? Like an app company that does computational photography apps for each kind of camera sensor?

The Pixel 4 also has a custom chip just for image processing which other phones do not, so you can't just port the code over to other phones.

  So the pixel 4 gcam port already works pretty ok on many phones. The image processing speeds up the processing - I admit to it. But we have the 855 flagships which are probably a few seconds behind. This is ok with us. I'm asking if anyone can hit the quality even given 5x more processing time .
