论文摘要
深度学习的高级面部识别，以实现前所未有的准确性。但是，了解面部的本地部分如何影响整体识别性能仍然不清楚。除其他外，面部互换已被试验到这一目的，但仅是整个脸部。在本文中，我们建议交换面部零件，以剥夺不同面部零件（例如眼睛，鼻子和嘴巴）的识别相关性。在我们的方法中，通过拟合3D先验来交换从源面转换为目标的零件，该零件在零件之间建立密集的像素对应关系，同时还要处理姿势差异。然后，无缝克隆用于在映射的源区域和目标面的形状和肤色之间获得平滑的过渡。我们设计了一个实验方案，该协议使我们能够在通过深网进行分类时得出一些初步结论，表明眼睛和眉毛区域的突出性。可在https://github.com/clferrari/facepartsswap上找到代码
Deep learning advanced face recognition to an unprecedented accuracy. However, understanding how local parts of the face affect the overall recognition performance is still mostly unclear. Among others, face swap has been experimented to this end, but just for the entire face. In this paper, we propose to swap facial parts as a way to disentangle the recognition relevance of different face parts, like eyes, nose and mouth. In our method, swapping parts from a source face to a target one is performed by fitting a 3D prior, which establishes dense pixels correspondence between parts, while also handling pose differences. Seamless cloning is then used to obtain smooth transitions between the mapped source regions and the shape and skin tone of the target face. We devised an experimental protocol that allowed us to draw some preliminary conclusions when the swapped images are classified by deep networks, indicating a prominence of the eyes and eyebrows region.
