Title: Dual-Domain Diffusion Based Progressive Style Rendering towards Semantic Structure Preservation. Abstract: In this paper, we propose a Dual-Domain Diffusion based Progressive Style Rendering (D3PSR) method to achieve style rendering from the semantic Domain A to the style Domain B. Different from the classic diffusion models, our model takes two unpaired images from two domains as inputs, and the output is obtained at the midst layer. With the benefits from diffusion models, a dynamic rendering process was leveraged to progressively incorporate the texture strokes from the style domain while preserving the semantic structure in the noise-adding steps. Our experiments shows that a range of artistic styles can be successfully transferred into the target images without breaking their semantic structures, demonstrating the merits of our new diffusion-based approach with beyond the state-of-the-art performance in style transferring. A further study utilized the similarity scores to measure such a diffusion-based process, showing how semantic structures were rendered in our progressive process in a quantitative view.
