Digital Processing Issues and Fixes: Topaz sneaks out Gigapixel AI update, 3X faster

[Mike Bedford]

Yesterday Topaz soft-released version 4.3.1 of Gigapixel AI, with the following features:


•Toggle in right panel to enable and disable Face Refinement


•Face Refinement will detect small faces (16x16px - 64x64px) and apply targeted improved upsampling


They are also aiming for 3X faster CPU processing.


Below is a screenshot of the new GUI with a 15-year old, 4MP image being treated with 4X magnification.

Pretty fabulous!

Thanks, I thought so too, considering the small area of the full image being processed.

See my blog (URL in sig) for more examples (including some fun ones!)

Update: Version 4.3.1 is being revised due to some issues with the Mac version (although the copy I updated to a few days ago still works fine), so watch for news in the next couple of days.

Final version 4.3.1 is now out, and is double-discounted for those of you who don't have it.

Have you tested it? 3x faster is a huge improvement. What does it require to get that extraordinary benefit?

This speed increase effort was aimed at CPU mode (which I never use, as my mighty MacBook Air has a decent GPU ;-)), but I am about to have some fun on a 17" 2008 MacBook Pro running Mojave...

Turns out I had Gigapixel 2.1.1 on the old MBP (which I successfully updated to 4.3.1), but we want to test 4.2.2 vs 4.3.1 in CPU mode. I was unable to do that as my main computer already had the latest version.

The official 4.3.1 release change log states:

Third party libraries for Gigapixel
Qt libraries
Lensfun Library
AI Model Update

If someone still has 4.2.2 installed and hasn't updated yet, please test in CPU mode vs. 4.3.2!

Cool technology based on your samples

Thanks Robert! I literally have more fun with this app than any other.
