Howdy! Pixelmator Pro 1.5.5 has just been released and it brings some significant improvements to ML Super Resolution and ML Denoise as well as two new Automator actions for those two features. Because seeing is believing, we thought we’d whip up a blog post with some examples to highlight the changes.

Fantastic update! Are you working on something that comes closer to Topaz's approach? Why is the Automator action limited to 3x increase? Can I input the values manually?

Closer in what way? As far as we've seen, their approach doesn't provide real-time (or close to real-time) feedback and that's what we'd be aiming for.

As for 3x — that's the most computationally efficient amount and that's how much the underlying algorithm increases every image, even if you choose a smaller size in the Image Size dialog. We simply reduce the result to the required size afterward using the Bilinear algorithm so you can use the Scale Images action to scale the image down. If you choose more than 3x, the algorithm runs twice, so you can simply apply the Increase Resolution of Images action twice to get the same result (and then use the Scale Images action to get an exact size).

Great update. Nice to see improvements and bug fixes as well as Automator actions. The Denoise does a good job now. Hopefully the edges and contrast could be improved but really good job.

Cheers to that!

Ah I understand. Yes their approach is very far away from being realtime. That's true. But what I meant was the way new texture is generated. I don't know how they do it but maybe you have the answer.
Would love to see this kind of batch processing inside of Pixelmator Pro to see an actual progress bar or something like that.

We can't know for sure what kind of approach they took but it doesn't really matter all that much — we plan to keep improving our algorithms (not just for ML Denoise) regardless. And if you ever find any images where you think we could do better (either generally, or compared with other apps), sharing one or two samples with us at support@pixelmator.com helps us a lot!

As for batch processing inside the app, a more refined photo-centric workflow sounds like something we should consider if/when we bring Pixelmator Photo to macOS. I think there's a lot of potential to do something very cool with it.
