Unfortunately, the face looks worse than the blurry original.
I looked at the retouched pic this morning during coffee. The brain was not 100% engaged at that time. Topaz did a decent job, but I too noticed the face/head issue.
After all of my chores were completed, I looked far closer at 100% sized retouched pictures posted by Keit II. I agree with you Pov2.
The face looks with lesser IA retouching quality than the MyHeritage image. I also notice a distinctive Halo around the head/hair area. It also looks heavily sharpened with artifacts of sharpening and noise. The My Heritage retouch doesn't have halos and sharpening issues.
Now, the background of the Topaz AI retouch looks a lot better. I do see sharpening artifacts in the topaz retouch. This could be as a result of a heavy hand editing in Topaz.
MyHeritage has a long way to go on landscape images. Topaz has a leg up on them on this point. We need a product that has the capability to do both. I'm not expecting miracles, just bring back some assemblance of sharpness without artifacts and over sharpening issues.
My picture of a landscape colorizing has something left to be desired.
AI is getting better. I like what Topaz has done, but we are several generations away from "Magic time" with AI producing better focused goof pictures. Topaz is pushing the envelope and I'm glad to see them do so. Eventually, in short time, they will crack the AI nut and bring forth a revolutionary product that will not only do background restoration, but facial restoration. MyHeritage is just the beginning.
A query to Keit II. Try using Gigapixel and blow up the original photo by a factor of 4. That is what MyHeritage does before performing the AI on it. Run the enlarged picture through Topaz AI, then reduce it back down to original size. Let's see the product result. It may be a more fair evaluation of Topaz when you work apples to apples with MyHeritage.
