Does anyone know which algorithm they use for super resolution in the camera app? I know they're using RAISR [0] for zoom in the previous version, seems like they have a new method now with multi image super resolution. I doubt it's anywhere near as good as a second camera with a different lens, so I don't understand why they won't include a second camera in the back like every other modern phone.

Another recent "super resolution" method (RAISR) from Google Research: https://arxiv.org/abs/1606.01299 https://research.googleblog.com/2016/11/enhance-raisr-sharp-... >Given an image, we wish to produce an image of larger size with significantly more pixels and higher image quality. This is generally known as the Single Image Super-Resolution (SISR) problem. The idea is that with sufficient training data (corresponding pairs of low and high resolution images) we can learn set of filters (i.e. a mapping) that when applied to given image that is not in the training set, will produce a higher…

Those looking for quantitative comparison of this against other techniques, it's on page 21 of the paper ( https://arxiv.org/abs/1606.01299 ) Edit: and to see for yourself in more detail there's https://drive.google.com/file/d/0BzCe024Ewz8ab2RKUFVFZGJ4OWc...
