QwenStyle: Content-Preserving Style Transfer with Qwen-Image-Edit

TL;DR

QwenStyle is a novel content-preserving style transfer model trained on Qwen-Image-Edit, capable of generalizing to unseen styles while maintaining high content fidelity and style quality.

Contribution

It introduces a new training framework and dataset for style transfer, enabling generalization to unseen styles with preserved content quality.

Findings

Achieves state-of-the-art results in style similarity, content consistency, and aesthetic quality.

Effectively generalizes to unseen styles without content degradation.

Utilizes Curriculum Continual Learning for robust training.

Abstract

Content-Preserving Style transfer, given content and style references, remains challenging for Diffusion Transformers (DiTs) due to its internal entangled content and style features. In this technical report, we propose the first content-preserving style transfer model trained on Qwen-Image-Edit, which activates Qwen-Image-Edit's strong content preservation and style customization capability. We collected and filtered high quality data of limited specific styles and synthesized triplets with thousands categories of style images in-the-wild. We introduce the Curriculum Continual Learning framework to train QwenStyle with such mixture of clean and noisy triplets, which enables QwenStyle to generalize to unseen styles without degradation of the precise content preservation capability. Our QwenStyle V1 achieves state-of-the-art performance in three core metrics: style similarity, content consistency, and aesthetic quality.
