摘要:

提出了一种在无约束二维图像中进行三维人脸形状和姿态估计的高效、全自动方法。所提出的方法联合估计一组密集的3D地标和面部几何形状,使用一个单一的通行证的修改版本的流行的“U-Net”神经网络架构。此外,我们提出了一种直接估计一组3D变形模型(3DMM)参数的方法,使用估计的3D地标和几何形状作为一个简单的线性系统中的约束。定性建模结果,以及定量评估预测的3D人脸地标在无约束的视频序列。

英文摘要:

An efficient, fully automatic method for 3D face shape and pose estimation in unconstrained 2D imagery is presented. The proposed method jointly estimates a dense set of 3D landmarks and facial geometry using a single pass of a modified version of the popular "U-Net" neural network architecture. Additionally, we propose a method for directly estimating a set of 3D Morphable Model (3DMM) parameters, using the estimated 3D landmarks and geometry as constraints in a simple linear system. Qualitative modeling results are presented, as well as quantitative evaluation of predicted 3D face landmarks in unconstrained video sequences.
