Official implementation of **[StoryDiffusion: Consistent Self-Attention for Long-Range Image and Video Generation]()**.
|
||||
|
||||
### **Demo Video**
|
||||
|
||||

||||

|
||||
|
||||
### 🌠 **Key Features:**
|
||||
StoryDiffusion can create a magic story by generating consistent images and videos. Our work mainly has two parts:
|
||||
1. Consistent self-attention for character-consistent image generation over long-range sequences. It is hot-pluggable and compatible with all SD1.5 and SDXL-based image diffusion models.
|
||||
2. Motion predictor for long-range video generation, which predicts motion between Condition Images in a compressed image semantic space, achieving larger motion prediction.
|
||||
|
||||
|
||||
|
||||
## 🔥 **Examples**
|
||||
|
||||
|
||||
### Comics generation
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
### Image-to-Video generation （Results are HIGHLY compressed for speed）
|
||||
Leveraging the images produced through our Consistent Self-Attention mechanism, we can extend the process to create videos by seamlessly transitioning between these images. This can be considered as a two-stage long video generation approach.
|
||||
|
||||
Note: results are **highly compressed** for speed, you can visit [our website]() for the high-quality version.
|
||||
#### Two-stage Long Videos Generation (New Update)
|
||||
Combining the two parts, we can generate very long and high-quality AIGC videos.

|
||||
|
||||
#### Long Video Result using Condition Images
|
||||
Our Image-to-Video model can generate a video by providing a sequence of user-input condition images.

Function invoked when calling the pipeline for generation.

Only the parameters introduced by PhotoMaker are discussed here.

For explanations of the previous parameters in StableDiffusionXLPipeline, please refer to https://github.com/huggingface/diffusers/blob/v0.25.0/src/diffusers/pipelines/stable_diffusion_xl/pipeline_stable_diffusion_xl.py
|

|

Args:
|
||||
input_id_images (`PipelineImageInput`, *optional*):
|
||||
Input ID Image to work with PhotoMaker.
|
||||
class_tokens_mask (`torch.LongTensor`, *optional*):
|
||||
Pre-generated class token. When the `prompt_embeds` parameter is provided in advance, it is necessary to prepare the `class_tokens_mask` beforehand for marking out the position of class word.
|
||||
prompt_embeds_text_only (`torch.FloatTensor`, *optional*):
|
||||
Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not
|
||||
provided, text embeddings will be generated from `prompt` input argument.
|
||||
pooled_prompt_embeds_text_only (`torch.FloatTensor`, *optional*):
|
||||
Pre-generated pooled text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting.
|
||||
If not provided, pooled text embeddings will be generated from `prompt` input argument.
|
||||
|
||||
Returns:
|
||||
[`~pipelines.stable_diffusion_xl.StableDiffusionXLPipelineOutput`] or `tuple`:
|
||||
[`~pipelines.stable_diffusion_xl.StableDiffusionXLPipelineOutput`] if `return_dict` is True, otherwise a
|

`tuple`. When returning a tuple, the first element is a list with the generated images.
