**In one line:** Inpainting, outpainting, background removal, style transfer, AI upscaling.

## Theory, aesthetics & inspiration

A working toolkit turns generation into surgery. Inpainting masks a region and regenerates only what lies beneath it; outpainting extends the canvas past its original edges, inventing plausible continuation; background removal isolates figure from ground. Style transfer recasts content in another visual idiom, while AI upscaling — super-resolution — synthesizes convincing detail to enlarge an image. Structural fidelity through such edits owes much to ControlNet, introduced by Lvmin Zhang and colleagues in 2023, which conditions a diffusion model on a pose, edge map, or depth so composition survives a change of style. Each tool teaches a distinct way of seeing: where to cut, where to extend, and above all what to preserve.
