描述了一种用于定义面部原型的技术，该技术支持沿着“面部空间”中的可量化维度进行变换。示例说明了如何使用形状和颜色信息来执行预测性别和年龄转换。我们描述的过程从创建面部原型开始。一般来说，原型可以定义为包含跨一类对象的一致属性的表示。一旦我们获得了类原型，我们就可以获取一个缺少一些信息的示例，并用原型信息对其进行补充。实际上，这“添加”了缺失信息的平均值。我们使用这个概念通过包含来自相关原型的颜色信息将灰度图像转换为全彩色。还可以推断出一个类中两个组之间的差异。可以为每个组形成单独的原型。随后可以使用它们来定义一个转换，将一组实例映射到另一组的域上。本文详细介绍了我们用于转换面部图像的过程，并展示了如何使用它来改变感知的面部属性。< >
A technique for defining facial prototypes is described which supports transformations along quantifiable dimensions in "face space". Examples illustrate the use of shape and color information to perform predictive gender and age transformations. The processes we describe begin with the creation of a facial prototype. Generally, a prototype can be defined as a representation containing the consistent attributes across a class of objects. Once we obtain a class prototype, we can take an exemplar that has some information missing and augment it with the prototypical information. In effect, this "adds in" the average values for the missing information. We use this notion to transform gray-scale images into full color by including the color information from a relevant prototype. It is also possible to deduce the difference between two groups within a class. Separate prototypes can be formed for each group. These can be used subsequently to define a transformation that will map instances from one group onto the domain of the other. This paper details the procedure we use to transform facial images and shows how it can be used to alter perceived facial attributes.< >
