摘要
本篇論文將說明如何使用三維臉部資料覆蓋影片中的二維人臉，並為 了使臉部覆蓋自然，所做的多項預處理。此外為了確保三維資料在裁 切時不會造成太大的形變，因此本研究中我們使用保角映射。由於二 維與三維資料分別有不同的位置與大小，本論文將說明如何使用仿射 轉變解決此問題，讓兩種資料保持某種程度的一致性。最後，人們關 心的議題仍是如何讓臉部的覆蓋看起來更加自然。因此我們嘗試了多 種方法使顏色混合，並且將兩種不同膚色的臉部實行色彩調整，讓兩 張臉的膚色相近。然而只有調整膚色是不夠的，臉部邊界的線條仍然 很明顯，所以我們也同時將臉部邊界的線條模糊化，讓整體臉部的覆 蓋更加自然。

This paper will explain how to use 3D facial data to cover 2D human faces in the film. In order to make the face cover naturally, we need to do several preprocessing. To ensure that the 3D data will not cause deformation when cutting, so in this study, we use conformal mapping. Since the 2D and 3D data have different positions and sizes, this paper will explain how to use affine transformation to solve this problem. In addition to this, people still concern about how to make facial coverage look more natural. Therefore, we tried a variety of methods to mix colors, and color-adjust the faces of two different skin to make the skin of the two faces similar. However, it is not enough to adjust the skin color. The lines of the face boundary are still very obvious, so we also blur the lines of the face boundary to make the overall face coverage more natural.
