# Understanding Diffusion Models
What are Diffusion Models?
Basic Concept
Diffusion models operate by gradually transforming digital 'noise' into coherent and detailed content, enabling the creation of diverse visual outputs. The process involves iteratively adding Gaussian noise to an image and then learning to remove it through a reverse diffusion process.
Forward and Reverse Diffusion Process (opens new window)
In the forward diffusion process, diffusion models add noise to clear images, creating a path for creativity. This noise is then reversed in the backward diffusion process, resulting in the generation of high-quality images with intricate details.
How Diffusion Models Work
Adding and Removing Noise
One key aspect of diffusion models is their ability to add controlled noise to images systematically. By understanding this mechanism, creators can manipulate the level of noise added, influencing the final output's uniqueness.
