导语:在数字化时代,个性化书写风格的需求日益增长。华南理工大学、新加坡国立大学、昆仑万维以及琶洲实验室的研究者们近日在ECCV 2024会议上提出了一种新型风格化手写文字生成方法——一眼临摹AI,该技术仅需单张参考样本即可模仿用户的书写风格,支持英文、中文和日文三种文字。

随着人工智能技术的不断发展,手写体自动临摹成为一项有趣的研究课题。华南理工大学、新加坡国立大学、昆仑万维以及琶洲实验室的研究者们提出的一眼临摹AI,旨在为用户提供更加高效、便捷的书写风格模仿体验。

与传统笔迹模仿技术相比,一眼临摹AI仅需用户提供单张书写样本,即可模仿出符合用户书写风格的电子字体。该字体可用于社交和办公软件中,帮助用户更好地表达个性和传递情感。

为了实现这一目标,研究者们提出了一种风格化的手写文字生成模型(stylized handwritten text generation method),该模型能够从单张手写样本中提取用户的书写风格,进而合成任意书写内容的手写笔迹。

为了解决单张样本图像中存在的背景干扰问题,研究者们对样本进行高低频分离,发现书写样本的高频成分中具有清晰的文字轮廓,蕴含着显著的书写风格模式。基于这一观察,一眼临摹AI引入个人笔迹的高频成分来增强用户书写风格的提取。

在具体实现上,一眼临摹AI采用了以下技术方案:

  1. 拉普拉斯风格增强模块:利用拉普拉斯算子获取原始样本的高频成分,并从高频成分中提取出判别性强的风格模式。

  2. 自适应门控机制:通过多个可学习的门控单元,自适应过滤空域风格特征中的背景噪声。

  3. 风格-内容融合模块:将内容信息和风格信息融合后再注入扩散模型,引导后续的文字生成过程。

实验结果表明,一眼临摹AI在多个英文、中文和日文数据集上都取得了优异的临摹性能,尤其在仅需一张参考样本的情况下,其表现优于之前依赖十几张参考样本的SOTA方法。

总结:

一眼临摹AI为用户提供了更加高效、便捷的书写风格模仿体验,有助于在数字化时代更好地表达个性和传递情感。随着技术的不断进步,未来有望在更多场景中得到应用。
