    Enhancing image resolution software?

    so i use GIMP to enhance/increase size of my images when i need to but usually the program messes up the fine details of the image and therefore ruins it. obviously it does a better job than Paint but still i would prefer i lost no quality in the image. is there a software that can increase the image's resolution with high detail? thanks a lot

    First of all, increasing image resolution while maintaining high detail or enhancing detail is impossible. The reason why image is blurred when you stretch the size of an image is due to the fact your software calculates and fill in unavailable data, the detail information you are looking for never existed and will not magically appear. There are numerous ways to "enhance" the quality to make it look less blurry but it doesn't really solve actual problem.

    TL;DR - Always go from large to small resolution and not the other way around unless you are dealing with a vector graphic.

    Unless you have a vector image you can't. CSI isn't real life.

    Some programmes allow you to make vector images out of ordinary ones, though. They're not perfect, but they will often allow you to increase the size (if not altogether massively) without any really visible loss of detail. I use Adobe Illustrator on occasion for this. You basically tell the programme to make a 'drawing' of the picture in question, but make it as detailed as the programme can. Sure, it might take a minute or two to work on, but the result is probably the closest thing you can find to a vector image of an ordinary one.

    Image enhancing software exists, based upon very complex math and requiring A LOT of cpu power, we have one in my lab (developed in-house).

    Comercially available? Dunno.
    I liek fysix

    Sounds legit.

    You can't just magically increase resolution with pixel-based images without quality loss, vector would be your best shot.

    You can, it is called statistics.

    Nope. Lets say there's a dot on my image, 2 by 2 pixels. What is it? A bug? A speck of dirt? A piece of dust in the lens? A candy wrapper? A piece of cat's poop?

    im pretty sure Adobe had some Photoshop CS6 solution to CSI's Image resolution enhancement. It wont enhance it enough to see a person's skin cells though.

    For what it's worth, photoshop's (5.5) image size -> increase size + filter -> surface blur does a decent job of it. But, as others have said, nothing's great at it.

    Yes that is why you don't do statistics on 2 numbers....
    Google monte carlo methods imaging.

    What you're talking about is artificially increasing resolution by having the program "guess" what it would look like at a higher resolution.

    An accident is something that you did not mean to do at all. A mistake is something that you regret doing.

    so there are softwares that are able to shrink down but still keep their detail? sometimes when i shrink down some of my stuff in the preview it looks perfect but once i click the OK it just blurs everything.

    so what softwares do i need to use to have better lager to small? too bad we don't have CSI stuff yet, they could be put into better use than a bad drama.
