这篇文章介绍了模仿传统铜版雕刻的数字面部雕刻的基本技术。受传统技术的启发，我们首先建立了一套基本规则，这要归功于在原始照片的顶部建立了单独的雕刻层。根据简单的合并规则和专门为此目的引入的范围移位/缩放蒙版合并单独的图层。我们通过一组黑白和彩色版画来说明所介绍的技术，展示了不同的特征，如雕刻特定的图像增强，不同规则的雕刻线与中间色调混合，雕刻线的不规则扰动等。我们引入了雕刻风格的概念，它包括一组独立的雕刻层以及一组相关的范围移位/缩放蒙版。雕刻风格有助于将一个雕刻的外观和感觉移植到另一个雕刻。一旦预定义的可映射的雕刻风格和适当的用户界面的不同库添加到基本系统，从一个简单的数字照片开始，生产一个体面的凹版将是几秒钟的问题。在这个贡献中描述的雕刻技术为数字艺术开辟了新的视角，为雕刻家的工作增加了前所未有的力量和精度。
This contribution introduces the basic techniques for digital facial engraving, which imitates traditional copperplate engraving. Inspired by traditional techniques, we first establish a set of basic rules thanks to which separate engraving layers are built on the top of the original photo. Separate layers are merged according to simple merging rules and according to range shift/scale masks specially introduced for this purpose. We illustrate the introduced technique by a set of black/white and color engravings, showing different features such as engraving-specific image enhancements, mixing different regular engraving lines with mezzotint, irregular perturbations of engraving lines etc. We introduce the notion of engraving style which comprises a set of separate engraving layers together with a set of associated range shift/scale masks. The engraving style helps to port the look and feel of one engraving to another. Once different libraries of pre-defined mappable engraving styles and an appropriate user interface are added to the basic system, producing a decent gravure starting from a simple digital photo will be a matter of seconds. The engraving technique described in this contribution opens new perspectives for digital art, adding unprecedented power and precision to the engraver's work.
