DF-ACBlurGAN微拓扑周期图案生成
提出DF-ACBlurGAN，一种结构感知的条件GAN，通过频域重复尺度估计、尺度自适应高斯模糊与单元重构显式建模长程周期性。能在弱监督与类别不平衡下、结合实验生物响应标签，生成可控重复尺度、间距与边界一致性的生物材料微拓扑设计，较传统生成方法在重复一致性和结构可控性上表现更好。

Abstract: Learning to generate images with internally repeated and periodic structures poses a fundamental challenge for machine learning and computer vision models, which are typically optimised for local texture statistics and semantic realism rather than global structural consistency. This limitation is particularly pronounced in applications requiring strict control over repetition scale, spacing, and boundary coherence, such as microtopographical biomaterial surfaces. In this work, biomaterial design serves as a use case to study conditional generation of repeated patterns under weak supervision and class imbalance. We propose DF-ACBlurGAN, a structure-aware conditional generative adversarial network that explicitly reasons about long-range repetition during training. The approach integrates frequency-domain repetition scale estimation, scale-adaptive Gaussian blurring, and unit-cell reconstruction to balance sharp local features with stable global periodicity. Conditioning on experimentally derived biological response labels, the model synthesises designs aligned with target functional outcomes. Evaluation across multiple biomaterial datasets demonstrates improved repetition consistency and controllable structural variation compared to conventional generative approaches.
