Abstract
A diffusion model is provided with a reference image and a text prompt, and generates output images having content specified in the prompt and style characteristics represented in the image. The reference image is encoded to generate multiple image embeddings. The prompt is encoded to generate a text embedding that is separate from the image embeddings. After each denoising step of the diffusion model, the text embedding is used to perform a first cross-attention operation on the denoising output, and the image embeddings are used to perform a second cross-attention operation. During earlier denoising steps, the second cross-attention operation is associated with a low weight parameter, causing the operation to have a smaller effect on the output image. During later denoising steps, a high weight parameter is used. In some cases, the input image for the model may be generated by performing a diffusion process using the reference image.
