Laplacian diffusion for generating images

A system, comprising:

• one or more memories storing instructions;
• and
• one or more processors that are coupled to the one or more memories and, when executing the instructions, are configured to:
• perform, based on one or more inputs, one or more first denoising diffusion operations using a first trained machine learning model to generate a first image at a first resolution, and
• perform, based on the one or more inputs and the first image, one or more second denoising diffusion operations using a second trained machine learning model to generate a second image at a second resolution.
