Many of us have the need to upscale the resolution of SA images, eg from 1000x1000 to 6000x6000 pixels. But that task is very demanding, since the second upscaled image will have 36 times as many pixels as the lower-resolution image. How can sharpness etc be preserved?
Before now, my go-to program for this kind of task was Photozoom Pro 7, which worked as well as anything else I'd tried. All such programs work by interpolating new pixels in between the initial ones. However, this new program, A.I. Gigapixel, works on a completely different principle. It uses an artificial intelligence neural net that has been trained over many thousands of previous pictures, so that it knows, just from a few initial pixels, which actual object configuration was most probably represented by them. Then, in the final image, it replaces those few pixels with a high resolution image of the object configuration it has guessed.
Quite honestly, I'm amazed at how well this works on typical images--I haven't been able to fool it yet into representing the wrong actual configuration, and I've never seen such sharpness in results before either. As a quick test, see the sample picture below of the same highly magnified area from 2 upscaled 1000-->6000 pixel images, with the Gigapixel result on the left and the Photozoom Pro 7 one on the right--there's simply no comparison.
A.I. Gigapixel has only just been released--yesterday there was an intro webinar with many examples, follow it from my link at
Also this is time-sensitive, because Topaz are offering 20% off the price only until the 27th of this month, use coupon name ‘GigaGreg’. A free 30-day trial is also offered, which is how I've been able to test it so quickly.
