Lai Thai represents a key aspect of Thailand’s artistic and cultural identity, with its sophisticate patterns serving as a hallmark
of the nation’s aesthetic heritage. Mastering this art form is a demanding discipline, however, and requires a deep and
nuanced understanding of its extensive vocabulary of motifs and compositional principles. Consequently, the ability to
create authentic Lai Thai has remained largely inaccessible to the general public, making it exceptionally challenging for
new generations to learn and creatively engage with this vital component of cultural heritage. To address this challenge,
we present LaiThaiGen, a framework that makes it easy for anyone, regardless of their artistic ability, to turn a simple line
drawing into high-quality Lai Thai designs (a traditional Thai ornamental art form), while preserving their original structure
and composition. Our contributions are (1) a high-quality dataset of Lai Thai images curated from publicly available sources,
paired with synthetically generated badly drawn sketches (2) a diffusion-based approach to transform a simple sketch into
a refined art that emulates the key characteristics of Lai Thai art form, allowing intuitive generation in Lai Thai style from
minimal user input; and (3) Inception scores and qualitative results show that LaiThaiGen outperforms standard image-toimage
translation methods in realism and artistic fidelity. We hope that our approach can help preserve the cultural heritage
of Thai line art by simplifying the drawing process, making it accessible for a wider audience to explore and create authentic
designs.
