Inpainting algorithms

Definition

Inpainting algorithms are computational techniques used to reconstruct or fill in missing or corrupted parts of an image. These algorithms leverage information from surrounding pixels to create a seamless and coherent restoration, making them essential in the realm of photo and video editing. By utilizing machine learning and AI, inpainting algorithms enhance image quality and provide tools for artists and editors to creatively manipulate visuals.
