The core principle of intelligent redrawing (img2img) is to add a certain level of noise to the original image and then have the diffusion model progressively denoise and restore it, rather than generating from pure noise.

Verified扩散模型的核心原理分为前向扩散过程（逐步添加高斯噪声）和反向去噪过程（从噪声中还原图像）两个阶段79% similarVerifiedThe core idea of diffusion models originates from non-equilibrium thermodynamics: during the training phase, Gaussian noise is gradually added to clear images, and during the inference phase, noise is progressively removed from random noise in reverse to restore the image.74% similarVerifiedDiffusion models surpass the previously dominant GAN architecture in detail fidelity by learning the reverse process of gradually restoring images from noise.74% similar
