The software itself is really very simple. It does not say that it recovers them from the original image.Īmateur photographers and novices might be amazed at how AI Gigapixel can rescue their dodgy low-res images, but experts and serious photographers aren’t likely to be in this position in the first place, or as easily impressed by its results.
Note that it ‘recreates’ missing details using AI image analysis. Topaz Labs explains that AI Gigapixel “uses the power of artificial intelligence to accurately recreate missing details in your images” and that it is “trained on millions of images using deep learning technology.“ In fairness to AI Gigapixel, what it does is actually slightly different. The information that’s there is the only information there is. It doesn’t have any latent, hidden data waiting for a super-smart algorithm to bring out. But look, a low-resolution image has a fixed amount of information. Or software that can restore missing detail in low-resolution images.Īrtificial Intelligence does seem to have become a byword for modern magic, a technological touchstone for folk looking for miracle cures. Once, people were taken in by magical elixirs of life, now it’s more likely to be perpetual motion machines or giant telephoto zooms for your smartphone that can see the moons of Jupiter. Sceptics will take claims about blow-up software with a pinch of salt. There are other software tools that do this, including ON1 Resize and Alien Skin Blow Up, and these concentrate mostly on preserving sharp edges in blow-ups, where regular interpolation algorithms tend to soften them. You can do this using regular interpolation processes in Photoshop and other photo editors, but the results are not especially good, as Topaz Labs rightly claims, because you just get bigger, blurrier pictures. What is it?ĪI Gigapixel is a software interpolation tool designed to blow up photos that are too small into images large enough to print or display at larger sizes. If you must use this kind of software, then this is perhaps the most convincing on most kinds of subject, and that’s probably all you can say about it. It’s not magic, it’s a clever type of detail substitution we haven’t seen before.
AI Gigapixel’s blow-ups are sometimes jaw-dropping, sometimes just dodgy.
