- Abstract: Denoising diffusion models (DDMs) have led to staggering performance leaps in
image generation, editing and restoration. However, existing DDMs use very
large datasets for training. Here, we introduce a framework for training a DDM
on a single image. Our method, which we coin SinDDM, learns the internal
statistics of the training image by using a multi-scale diffusion process. To
drive the reverse diffusion process, we use a fully-convolutional light-weight
denoiser, which is conditioned on both the noise level and the scale. This
architecture allows generating samples of arbitrary dimensions, in a
coarse-to-fine manner. As we illustrate, SinDDM generates diverse high-quality
samples, and is applicable in a wide array of tasks, including style transfer
and harmonization. Furthermore, it can be easily guided by external
supervision. Particularly, we demonstrate text-guided generation from a single
image using a pre-trained CLIP model.

SR-DDPM is a class of generative models that produce high-quality images by reversing a noisy diffusion process.
By exploiting the similarity between diverse data distributions, our method can scale to multiple tasks without compromising the image quality.
We evaluate our method on standard image datasets and show that it outperforms both unconditional and conditional DDPM in terms of FID and SSIM metrics.
