I'm researching generative art using computers, and I'm looking to see if there's a more specific term for types of image manipulation techniques like ASCII art or photo mosaics that can narrow down my search. Basically it's anything that uses a real image as input and outputs something other than individual pixels from the image. Some examples would be or this plotter print of a woman.
My sense is that "generative art" is a phrase that properly describes what these techniques do. However, there are other generative art techniques that don't rely on images for input and have a more abstract art look to them when final images come out, so I feel like the term is more broad than the techniques I'm describing.
