基于扩散模型的甲骨摹本图像生成技术研究
- 分享到:
摘要：
甲骨摹本是甲骨文研究中的重要资料，主要用于墓写甲骨表面的轮廓、字符及裂痕等关键信息.然而，传统摹本制作过程耗时长、劳动强度大，且高度依赖专家经验,针对上述问题，本文提出了一种基于字符信息密度归一化的扩散模型训练策略，在有效提取字符纹理特征的同时，兼顾甲骨轮廓等整体图像纹理信息.此外，为满足摹本生成中对甲骨字符突出表达的需求，本文引人零终端信噪比机制以控制模型的分布差异性，实验结果表明，该方法在甲骨摹本生成任务中显著提升了图像生成质量与空间表达效率，为甲骨文字形研究提供了一种可靠的技术手段。
Oracle bone facsimiles are an essential resource in oracle bone inscription studies, serving to reproduce surface information such as contours, characters, and cracks of oracle bones. However, the traditional process of producing oracle bone facsimiles is tme-consuming. labor-intensive, and highly dependent on expert knowledge. To addres these challenges, this paper proposes a diffusion-model-based training strategy with character inlormation density normalization, which enables the effective extraction of fine-grained character texture features with the preservation global image textures such as contours. Fur-thermore, to emphasize oracle bone characters in facsimile generation, a zero-terminal signal-to-noise ratio mechanism is introduced to control distributional discrepancies during diffusion. Experimental results demonstrate that the proposed method achieves higher image generation quality and improved spatial efficiency in oracle bone facsimile generation tasks, providing strong technical support for oracle bone character form analysis.
