Inpainting
Inpainting is an image processing technique used to automatically fill in or reconstruct missing, damaged, or occluded regions of an image based on surrounding visual information, maintaining visual coherence. The technique can be implemented using traditional mathematical algorithms (such as partial differential equations) or deep learning models, and is widely applied in watermark and noise removal, damaged photo restoration, video editing, and image content generation.
Core Facts
Inpainting allows creators to modify only specific regions of an image while keeping the rest unchanged.
AI image expansion corresponds to the technical term Outpainting (drawing outward), which contrasts with Inpainting (restoring inward)

Timeline (last 90 days)
A typical image generation workflow in production is: explore composition at low resolution, then use ControlNet to constrain pose and structure, and finally fix error-prone areas through local inpainting.
Img2img is a technique that regenerates an image using an existing image as a reference input, while inpainting is a technique that regenerates only a specific region of an image.
Latent space masking is the underlying logic commonly adopted by advanced techniques such as ControlNet and Inpainting.
The core logic of inpainting is to modify only the area selected by the user while keeping the rest unchanged.
The technical principle of inpainting is to apply a complete noise-reconstruction cycle to the masked region during the denoising diffusion process, while locking the retained region to the original pixels through conditional constraints.
Inpainting allows creators to modify only specific regions of an image while keeping the rest unchanged.
There are two mainstream implementations of Inpainting: a dedicated Inpainting model trained specifically for the task, and local repainting using ordinary models via noise-blending techniques.
Inpainting allows users to select a specific region in an image and regenerate only that region while keeping the rest unchanged.
Key techniques in image editing include Inpainting, which uses a mask mechanism to designate the editing region; conditional control modules such as ControlNet to maintain structural consistency; and Cross-Attention mechanisms to align text instructions with image features.
Inpainting technology marks the areas to be modified with a mask; the model applies noise and regenerates only the masked portions, while areas outside the mask retain the original pixels.
