Revolutionizing Cultural Heritage Preservation with AI-Powered Embroidery Synthesis
This study introduces a novel diffusion model-based method to digitize Cantonese embroidery, a human intangible cultural heritage. By integrating lightweight LoRA fine-tuning, SAM semantic segmentation, and ControlNet multi-condition guidance, the method generates high-quality, ultrahigh-fidelity embroidery-style images. It addresses limitations of existing simulation techniques, such as insufficient stitch diversity and unnatural pattern transitions, achieving superior feature reconstruction and detail generation with limited data. The approach significantly outperforms existing methods across key metrics (LPIPS: 0.244; FID: 95.57; PSNR: 16.38) and offers remarkable visual and user evaluation advantages. This innovation provides a critical path for relic restoration, design reference, and intelligent manufacturing simulation, ensuring the digital preservation and innovative application of traditional craftsmanship.

Strategic Advantages for Cultural Institutions & Creative Industries
The integration of advanced AI for digital heritage preservation offers transformative benefits across various enterprise sectors, from museums to manufacturing.
Enhanced Preservation & Accessibility
Digitally preserving intricate cultural heritage like Cantonese embroidery ensures its longevity and global accessibility, circumventing limitations of physical degradation and traditional artisanal scarcity. This opens new avenues for educational outreach and historical research without risking original artifacts.
Accelerated Design & Innovation Cycles
AI-generated embroidery styles serve as invaluable design references, dramatically reducing the time and cost associated with manual prototyping. This enables designers in fashion and textile industries to rapidly iterate and innovate, bridging traditional craftsmanship with modern production demands.
Intelligent Manufacturing & Customization
The ability to simulate complex embroidery patterns with high fidelity directly supports intelligent manufacturing. It facilitates process simulation and production data integration, enabling automated embroidery machines to replicate traditional styles accurately and efficiently, offering unparalleled customization options for bespoke products.
Economic Revitalization of Traditional Crafts
By providing digital tools for creation and preservation, AI helps revitalize traditional crafts. This attracts new talent, broadens market appeal through digital products and experiences, and creates new economic opportunities for artisans to monetize their expertise in the digital realm.

This study presents a novel image generation method for Cantonese embroidery artistic styles, based on Stable Diffusion (SD), leveraging LoRA fine-tuning, SAM semantic segmentation, and ControlNet multi-condition guidance. This synergistic approach addresses key challenges in digital heritage preservation, including data scarcity, accurate texture reproduction, and semantic consistency.
A high-quality dataset of 494 Cantonese embroidery artworks was constructed, overcoming limitations of online image quality. It includes 45 thematic categories, with precise semantic labeling using WD14-tagger and manual correction. This meticulous data preparation is crucial for training robust AI models for specialized artistic styles.
The LoRA (Low-Rank Adaptation) fine-tuning method was applied to the Stable Diffusion 1.5 base model using the curated dataset. This plug-and-play approach efficiently adapts the large model to Cantonese embroidery textures with limited training data, achieving high-fidelity texture simulation while maintaining visual harmony. Optimal performance was observed at the 8th epoch with a weight of 0.9.
ControlNet provides multi-condition guidance (Depth, LineArt, Color) to preserve geometric structure and color consistency. SAM (Segment Anything Model) ensures high-precision spatial semantic constraints, preventing misplacement and refining local details. This combined guidance mechanism is critical for generating visually coherent and semantically accurate embroidery patterns.
The proposed method significantly outperforms baseline models (VGG19, CycleGAN, AdaIN, Cross-Image-Attention) across LPIPS, FID, and PSNR metrics, demonstrating superior texture reconstruction and detail generation. Qualitative analysis confirms its ability to reproduce unique silk textures and stitching patterns with natural color transitions, even at high resolutions.
Expert user evaluation validated the method's superior performance in craftsmanship reproduction, material texture realism, and color fidelity. The high inter-rater consistency (Alpha > 0.70) across all metrics underscores the robustness and practical applicability of the generated embroidery styles for digital preservation and innovative design.
