Splice, Focus and Relife: High-Resolution Periodic Pattern Generation

The printing and dyeing industry requires periodic and high-resolution patterns to ensure seamless designs on large fabric sections and high-quality final products. However, current manual approaches to pattern creation are time-consuming and labor-intensive. Leveraging powerful image generative models, such as Latent Diffusion Models (LDMs), offers a promising alternative, but challenges persist in generating strictly periodic and high-resolution patterns due to the inherent randomness and high computational demands of LDMs. In this paper, we propose a novel text-driven framework for generating periodic and high-resolution patterns. We introduce a new training-free Splice-and-Focus Mechanism, which enhances the model by constraining latent features and modifying the attention mechanism to produce natural and strictly periodic patterns. Additionally, we present a ReLife Pipeline, which integrates super-resolution and guided image synthesis to enhance pattern resolution while eliminating artifacts and distortions. Experimental results demonstrate that our framework produces patterns of superior quality.
