Accurate Story visualization requires several necessary elements, such as
identity consistency across frames, the alignment between plain text and visual
content, and a reasonable layout of objects in images. Most previous works
endeavor to meet these requirements by fitting a text-to-image (T2I) model on a
set of videos in the same style and with the same characters, e.g., the
FlintstonesSV dataset. However, the learned T2I models typically struggle to
adapt to new characters, scenes, and styles, and often lack the flexibility to
revise the layout of the synthesized images. This paper proposes a system for
generic interactive story visualization, capable of handling multiple novel
characters and supporting the editing of layout and local structure. It is
developed by leveraging the prior knowledge of large language and T2I models,
trained on massive corpora. The system comprises four interconnected
components: story-to-prompt generation (S2P), text-to-layout generation (T2L),
controllable text-to-image generation (C-T2I), and image-to-video animation
(I2V). First, the S2P module converts concise story information into detailed
prompts required for subsequent stages. Next, T2L generates diverse and
reasonable layouts based on the prompts, offering users the ability to adjust
and refine the layout to their preference. The core component, C-T2I, enables
the creation of images guided by layouts, sketches, and actor-specific
identifiers to maintain consistency and detail across visualizations. Finally,
I2V enriches the visualization process by animating the generated images.
Extensive experiments and a user study are conducted to validate the
effectiveness and flexibility of interactive editing of the proposed system.
