Diffusion Models in Vision: A Survey

Croitoru, Florinel-Alin, Hondru, Vlad, Ionescu, Radu Tudor et al.

Understand

Denoising diffusion models represent a recent emerging topic in computer vision, demonstrating remarkable results in the area of generative modeling.

  • A diffusion model is a deep generative model that is based on two stages, a forward diffusion stage and a reverse diffusion stage.
  • In the forward diffusion stage, the input data is gradually perturbed over several steps by adding Gaussian noise.
  • In the reverse stage, a model is tasked at recovering the original input data by learning to gradually reverse the diffusion process, step by step.
