PONE-D-25-11208R3Transformation of Artistic Style and Innovative Design of Oriental Folk Patterns Based on AIGC Technology—A Case Study of Zhuxian Town New Year Paintings from ChinaLatest supplementary materials

In response to the limited cross-domain innovation in the digitalization of traditional oriental folk art, this study takes the New Year pictures of China’s Zhuxian Town as a case. It develops a collaborative technical framework of combining the Liblib platform and a LoRA model to explore AI-generated digital re-creation of traditional art. A high-quality dataset was built through a three-stage process of image acquisition, multidimensional screening, and expert review. A three-layer keywords thesaurus was constructed through literature analysis, questionnaire surveys, and semantic clustering. Using a two-stage training strategy combining pre-training and fine-tuning, along with dynamic optimization, the model accurately captures the stylistic features of Zhuxian New Year pictures. The generated outputs integrate traditional aesthetics with modern design and are applied to cultural and graphic creative products. The results demonstrate the effectiveness of the proposed framework for preserving artistic style while enabling cross-domain innovation and offer a practical technical reference for the digital inheritance and modernization of related folk arts.
