Lately, I've been trying to increase the quality of some of my images. I discovered rather quickly however that you can't fundamentally improve the quality of an image and that this was a common issue when scaling pictures.
I understand that this issue is born out of the fact that a computer doesn't know what's actually happening in a picture i.e. A man holding up three or two fingers and therefore scaling makes the picture appear blurry.
So I was wondering whether there was a software that could break down images into separate colour layers, for example, an image of a fox being broken down into separate maps of orange, dark orange, darker orange and white. Once the image had been broken into these layers, could you then scale them in unison so that the image doesn't blur? This method allows the image to scale while remembering a colour maps shape and colour value.
Is this a known method and will it work?
