This task is complicated by the complex reflectance properties of human faces and the unknown types and numbers of light sources in the input photographs. Previous work makes several simplifying assumptions, such as Lambertian reflectance for faces [AGR96], simple analytic illumination models (usually Phong) and simple illumination (usually one ambient and one directional light) [BBPV03,BSVS04].Unfortunately, these simplifications make it hard to achieve photorealistic and geometrically accurate face models.

这项工作是由人类面部的复杂反射率工具和未知类型和数目的输入相片中的光源完成的。早期工作做出了简化的假设，比如面部传感器反射率[AGR96],简单分析照度模型（通常是多面的）和简易照明（通常一个是周围光线，一个是定向光线）[BBPV03,BSVS04].不幸的是这些简化使获得渲染引擎和几何学上精确的面部模型十分困难.
