I am searching for a simple and fast method (eg. through a filter) to convert low-resolution images objects' edges...

 

Hair apart, this is what I am searching for (simply a clean line, without fake sharpen/contrast effects):

Note: in this example, I am using a portion of a face but I am searching for something that works on any kind of object (a dress, a table a leg, etc.).

Your expectation is unrealistic.  In the images you posted it is obviously impossible to recreate the individual pieces of hair that form a »solid« strand in the lores image from that. (Unless you are speaking about a layered lores image in which the original image is embedded as a Smart Object, but I wouldn’t expect you do.)  You could check out Topaz Gigapixel, in some cases it might produce better results than Photoshop’s resampling methods.

Have you tried the new Neural Filter for JPG Artifact Removal?


By @kevin stohlmeyer

 

I've tried it, and I was actually very impressed. It absolutely works as advertised, and it will also remove some of the halos you can see here, which is specifically a jpeg compression artifact (not sharpening artifact).

 

But a one-click automatic solution to get perfectly crisp edges (like the examples) is IMO unrealistic. I would expect some further filtering to be required here.

Yes but that is not exactly what I am searching for, I am searching for something like a total redraw of the line...

Hi there,

 

Thanks for reaching out. We understand your concern and are here to help.

Which version of Photoshop are you using? As you know, Photoshop is very powerful software; there are hopes to get the picture back in form.

There are different tools and procedures to do it. I am listing a few youtube tutorials below; please have a look;

I think they recently released some facial reconstruction feature … but bear in mind: If an application creates detail for hair, eyelashes, irises etc. that is simply not present in the source image then the resulting image should be considered more like a painting than a photograph.
