Curious, does this use a publicly available model (such as real-esrgan), or is it a custom model? To reach 10x magnification, is 2x magnification simply consecutively repeated?

I'm also curious about this (as a researcher myself). It would be nice to know what model is used (or if this is actually novel[0]). It is also worth mentioning the legal issues of this, and since you are charging(?) for this, you can be in legal jeopardy[1]. The architecture might be under some license and if you tuned a model that might also be under a license (it is worse if these are not under a license!). Most r…

Thank you for your professional reminder. Currently, I am using a third-party API directly and haven't paid attention to specific licensing details. Your reminder has brought this to my attention, and I will make sure to address it. Thank you for the heads-up.

Tried it with some typical event photos of people that contain out-of-focus regions. Did a pretty terrible job. I.e. at 10k, you should see some skin structure but instead it was just color banding, eyelids had non-existing wrinkles added though etc. To the author: PM me and I send you some examples, if interested.

Skin texture is very hard it seems. I’m often developing raw photos and the noise reduction often remove skin texture too much. Especially when I was editing photos of our newborn, there is just so much little details that easily gets lost in noise reduction (or compression) that are very clearly visible to the eye.

Most enhancements involve noise reduction, which can indeed lead to some texture loss.

Great work man, i would love to know more about the process! did you take existing images and degrade them then use the high res version as a confirmation or how'd you do it?

In the demo image, I used a relatively blurry picture for enhancement, so the difference appears more noticeable.

I experimented with several images featuring people and pets. The processed results were so similar to the originals that it was difficult to discern any changes.

Your original image might already be quite clear, so a simple comparison makes it hard to notice differences. I've tested with some clear images, and the differences become more apparent when carefully compared.

After submitting an image, I'm prompted to authenticate with Google - but once I do, and return, I have to re-submit the image. Also, it does ... not do great with faces, but I also did not expect it to: https://imgur.com/a/GCLbMGp

Great suggestion! I’ve noted this issue and will work on improving the interaction.

For faces, enabling the "Enhance Portrait" option will yield better results.

However, the effect on your image isn't very noticeable even with the option enabled. I've tested other faces and observed a significant improvement with the option turned on. I'm currently unsure where the difference might be.

If I understand correctly, there are 5 free credits (= 5 images) when I create an account. Do you plan to offer more free credits over time? Or have a plan that doesn't require a subscription? The product looks very nice, but I'm not willing to get a monthly subscription for this (I could pay, but I have very occasional needs).

Great suggestion! I plan to add an option to purchase credits separately, which can be used indefinitely once bought. I'll release this feature as soon as it's developed.

I work with small details from large images so I need something that will enhance the to a nice, sharp final resolution when I need to enlarge it. This tool worked very well with the samples I provided it. Great job!

Glad to hear it's helpful to you!

10x res is a lot. Do you do it in a single shot, or do you use multiple smaller steps (e.g. hitting it with 2 4x enhancements for 16x the res)? Also: 12000 pixels is a 110 x 110 image. 12000 x 12000 would be 144 megapixels.

We completed it all at once.
