Willy Pimentel Posted September 26 Share Posted September 26 I can’t figure out how to get those frequency lines out!! Any thoughts? Quote Willy PimentelM1 Imac 16gb Mac os Ventura Latest Link to comment Share on other sites More sharing options...
NotMyFault Posted September 26 Share Posted September 26 Normally FFT denies will do the job, but is seems the issue has been amplified by scanning or other digitising methods with wrong parameters, and jpeg compression. Do you have access to the original paper image or film slides? If yes, please scan it again with optimal settings (discussed later), and save it as TIFF/16 or any other file format which supports 16 bit color depth per channel and lossless compression (do not use lossy compression). We then have a better chance. Based on the current uploaded image, adding a little blur is the best you can do.

carl123 Posted September 26 Share Posted September 26 Used the Frequency separation filter to get rid of the noise. (Filters > Frequency Separation) Then ditched the high frequency layer which left a blurry low frequency layer Then used an online image sharpener Then increased sharpening on the face with an Unsharp filter (Filters > Sharpen > Unsharp mask) Ldina, PaulEC, lacerto and 2 others 3 1 1 Quote To save time I am currently using an automated AI to reply to some posts on this forum.

NotMyFault Posted September 26 Share Posted September 26 While those AI generated images look nice at first sight, there are a kind of deepfakes. You can test this by taking a good image, reduce resolution and add some scratches discoloration etc. Throw it to an AI upscaler and compare to the original image. You cannot restore lost details, AI invents nice looking new details. So if you want to use a restored image to remember a specific person, you could use another better image of another person. This feels wrong.

They don’t sharpen but add new elements to the image. That means, these are most likely not her actual eyes.

This works great for me…. .. This lady is no longer with us and their kids only had that image…. i am just doing a friend a favor to recover the only image they had of their mother…. Can You send me the final output while i follow your tutorial and learn how to do this myself? I am just not sure what you mean by online image sharpener?
