S2ED: From Story to Executable Descriptions for Consistency-Aware Story Illustration

Summary

The S2ED (Story-to-Executable Descriptions) framework addresses the challenge of maintaining long-horizon coherence in multi-frame story illustration, which requires consistent character identity, layout, and affect across frames. Proposed as a training-free, model-agnostic, prompt-layer solution, S2ED converts a complete story into a sequence of explicit, editable executable descriptions. It operates by coordinating three distinct agents that segment the narrative, establish canonical character attributes, and enhance spatial and affective cues. This design facilitates interpretable prompt-carried state propagation and allows for local edits to correct inconsistencies without needing to retrain the underlying image generator. Experiments on the Flintstones and Shakoo Maku datasets demonstrate that S2ED significantly improves sequence-level consistency and character fidelity compared to strong prompting, large-model planning, and a reference training-based method, as confirmed by both automatic metrics and human judgments. The framework has also been integrated into an end-to-end system for generating children's illustrated storybooks.

Key takeaway

For AI Engineers developing multi-frame image generation systems, S2ED offers a robust, training-free approach to ensure long-horizon consistency. You should consider integrating prompt-layer frameworks like S2ED to manage character identity, layout, and affect across sequences. This allows for targeted local edits to correct visual drift without the computational cost of retraining large models, significantly streamlining your workflow for applications like illustrated storybooks.

Key insights

S2ED uses a training-free, prompt-layer framework with three agents to generate consistent multi-frame story illustrations from text.

Principles

• Multi-frame consistency needs explicit state propagation.
• Decomposition into narrative, character, and spatial cues aids coherence.
• Prompt-layer control enables local edits without retraining.

Method

S2ED coordinates three agents for narrative segmentation, character attribute grounding, and spatial/affective cue enrichment, converting stories into editable executable descriptions to ensure consistent multi-frame rendering.

In practice

• Generate consistent character illustrations across story frames.
• Repair illustration drift via local prompt edits.
• Automate children's storybook illustration.
