Topaz Gigapixel AI is a program based on neural networks to increase the size of photos without loss of quality (in fact, of course, with minimizing such losses). After discovering it for myself, I decided to experiment and eventually found out that when the photo is enlarged several times (I used 4x magnification) with this program, and when it is subsequently reduced to the original size by Photoshop, its detail increases, and also the nasty grain disappears. I did all this on uncompressed JPEG. Most likely, such results can be achieved by combining several filters in Photoshop, but here everything is simply done in just a couple of clicks. The program is hardware-intensive and costs$ 100 (only 1.5-2 times more than PS5 games). A lot, but who here, I wonder, is the same photoshop licensed, and who - not so much? Anyway, I won't post the download link, otherwise it might be against the rules of the forum. Find the program yourself is not difficult (you can also view the wall of the group "Daz3D and Sculptris-content, guides, video tutorials" Vkontakte... ), but buy it... for some reason, my official website didn't open. And now for some examples.

Cosmopterix sibirica-you can see that the orange scales have become more prominent, and the grain has disappeared-compare the hairs on the leaf (it seems to be Inula helenium) to the left and right.

Heliozela sericella - I definitely did not reduce this photo when editing in comparison with the original on the camera's memory card, the butterfly is very small. You can see that the graininess has disappeared, and the detail has improved somewhat.

Aplocnemus sp. - the photo improved less. The beetle twitched slightly when shooting. You can compare the hairs on the right and left. For scientific purposes, perhaps the program is not suitable-what if some extra bristles come out where they are not? It's up to the experts to judge.

Tinea pallescentella, photo by NakaRB. On his Flickr page, it says that the photo was taken with a combination of 12 frames - I didn't use this method and don't have a good idea of how it works, but apparently it allows you to achieve higher detail and get rid of graininess. Anyway, here you can see that the detail has still increased significantly after processing, but already on the verge of oversharp, and the scales look slightly unnatural.

This is the same photo in the editor. The red arrow shows the type of photo transformation when magnified (Compressed), which is optimal for the above manipulations. In general, the interface is intuitive, and if you read some manual, you can probably make even better photos.

Finally, the landscape is magnified many times in Architectural mode. The oil painting turned out...

- But I would like to see 100% of the crop.

- And what is the demand for hardware expressed in: on a weak one, it refuses to start, crashes, or just works slowly?

"Is it like what's on the left is miraculously created from what's on the right?" The legend is fresh, but hard to believe...

-I don't quite understand, if anything - these are fragments of the original and improved photos cut out at a scale of 1:1, which may have slightly deteriorated during loading, but molbiol doesn't compress images additionally.

- I don't know, my hardware is not bad, I just wrote it as a fact, this is not my personal experience. On the page below, the recommended requirements indicate that you need 4GB+ of video memory and i7/i5 2015+. https://help.topazlabs.com/hc/en-us/article...m-Requirements-

- yes! This is also just a screenshot. A neural network is such a neural network. The question is what details really exist, and what details she thought up. Just on the landscape, you can clearly see various interesting artifacts, although the processing mode is different there.

I ran it on a GT8500 with 256MB of memory

In general, by the way, you can order a trial on the site, and in fact it is vidyukha that is important for this program, and of course in its original state it crashed with an error at the first launch. Percent I have Ryazan 4GHz 4 buckets and 8GB of RAM, at the maximum AI quality settings, the photo that is posted here was rendered for 12 minutes (!!), and with the option turned off, 2 minutes.
The first photo is the original, the second is the disabled option max. quality, the third one is on.
In general, this is something like an advanced shumodava / tsifrozuma, in modern mobile phones this is already used, and soon the cameras will work on this. The program is certainly super, but expensive(although it costs 69 pupaars and not 100
