A.I. Gigapixel--an Innovative Upscaling Program

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.

thanks for your note on this, sounds interresting

Thanks Max, I hope you'll give it a try--seeing is believing!

Have you tried ON1 Photo Raw?

I have found the results incredible.

Paul

Thanks Paul, I do have ON1, but haven’t tried the Resize module yet—glad it works so well for you.  But Gigapixel is a completely different beast.  Another example:  I have a medium resolution (4000x) image with some imperfections.  If I downsize it to 1000x, then upscale it back with Gigapixel, the result is BETTER than the original—the imperfections have been removed!  No conventional upscaler could do that.

Agree that the results are great - best I have seen. Useful even at 400%, but there is a huge bug that causes the output size to be different from that requested by the user. I spoke with Topaz and they acknowledged this and I thought it would be fixed in the inline release, but it wasn't. And you cannot change the aspect ratio and resize at the same time - those might be the conditions under which the output does not match the user's requested values. But yes, a great tool otherwise.

is it possible to convert to vector? As we know, vector are better than raster when we talk about size we need

But even if you could convert to vector, you wouldn't see the improvements that Gigapixel can produce.  Eg a distant cell tower or reflector dish may be just a blur in your image, but it can intelligently produce a larger image that looks much more like those originals.  IE it is actually adding information that isn't in the original image--vectors can't do that.

Thanks John.This tool is very usefull. 

Hi John, thanks for posting this info.

I downloaded trial Mac version. I made different tests. When I take a detail of a portrait picture, exemple eyes, so yes, AI giga brings a good result, better than Artis Software Super Resize that I'm using.

But if you want to enlarge all the picture, the result is not better than Super Resize, that works more faster than AIG. And I'm not limited to 600%. I just tested 1500%. My source was a 1600x1307 picture and the result was 24000x19605 png file.

Super Resize and AI Giga at last


Thanks Bernard.  As long as Giga has good results, speed is unimportant to me--I'll mainly use it in batch mode while doing other things.  Also, Giga can do 1500% in two passes--first 600%, and second 250%, so there's no upper limit.  Give it a try, and see if it compares well!

PATH START REGIONISATION

Please i'm working on a project using one of the regionization preset and i want the region i draw to be filled with the part of the image brush that best match or suits the source image. I'm using image folder brush and anytime i draw the region to be filled with the brush, it will be filled with parts that i dont want.Then again i'm using RGB Mapping under the Brush control panel.Could you please help me out.See More
