I draw your attention to such unpleasant effects in the operation of the SharpenAi system. The best quality results of fixing focus and blur defects in this program are obtained in Stabilize mode. But in this mode it is very clearly visible that the image is unsuitable for commercial use. Vertical stripes appear throughout the image and colored borders around contrasting parts (outside the object on a white background, indicated by an arrow).
I also want to draw your attention to the color noise arising in the image. I perfectly understand the logic of sales management, where the normal ability to remove any noise from SharpenAi, which worked great when I bought this program and served as a double incentive to buy (I often need a good noise reduction), suddenly disappeared with the advent of the DeNoiseAi program, because they thought that they will interfere with the sales of the new program. However, since I myself am gradually getting into the understanding of AI development, I already understand that the decision to cut the skill of good noise reduction in a sharpening algorythm is a crime in relation to getting a good result, because it is impossible to become a world champion when run along the track on one leg. original in Sharpen Ai
I used the original tif file and Stabilize creates vertical stripes in high contrast areas as profiwork showed. I have attached the 100% crop with arrows to show the results. I’m on a Windows 10 PC with a Radeon RX580 GPU.
In cpu mode works better. Problem in GPU mode more hardly. can’t add image, use this link
If you ask what kind of strange method this is for detecting image defects, then I note that this is something like a standard for checking image quality for commercial work.
