Improve low-resolution images: how to quickly clean the edges of objects?

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.

Thanks, maybe topaz could be the right solution.

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.

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;

Thanks but I have already seen them, I am searching for something like a total redraw of the line...

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.
