I don't think the Pixel Visual Core is supposed to do anything new or revolutionary -- the primary purpose is to do these old things FASTER for the user.

- abainbridge 9y agoBut a simple histogram stretch can be done with very little processing power by modern standards. 50 ms on one core of the application processor would be enough. I think they just chose bad examples. The results from this Google Research blog post are much much more impressive: https://research.googleblog.com/2017/04/experimental-nighttime-photography-with.html https://research.googleblog.com/2017/04/experimental-nightti... I wish my smartphone could do _that_ automatically.
- phs318u 9y agoThanks for that. That was amazing.
- dharma1 9y agoYou end up with a lot more noise with simple histogram adjustment from a single image, plus the dynamic compression to a final 8bit image won't look as good for many use cases. Exposure fusion from multiple images has much higher usable dynamic range and lower noise.
- glenneroo 9y agoFaster and supposedly uses much less power. > Using Pixel Visual Core, HDR+ can run 5x faster and at less than one-tenth the energy than running on the application processor (AP).
- em3rgent0rdr 9y agoNot just faster but more energy efficient I presume. That's especially important when taking long videos.
