摘要:

脸是我们与周围世界交流的最重要的东西之一。它也形成了我们的身份和表达。人脸结构估计是计算机视觉的一项基本任务,在人脸识别和医疗手术等不同领域都有应用。最近,深度学习技术在从平面图像进行3D人脸重建方面取得了显著的成果。这些技术的主要挑战是对大型3D人脸数据集的迫切需求。通常,这个挑战是由合成人脸生成处理。然而,合成数据集遭受不可能的面孔的存在。在这里,我们提出了一个人脸流形学习方法的合成多样的人脸数据集生成。首先,将人脸结构分为形状组和表情组。然后,利用完全卷积的自动编码器网络来处理不可能的人脸,同时保持数据集的多样性。仿真结果表明,该方法能够对严重受损的人脸图像进行去噪。所生成的数据集的多样性进行了定性和定量评估,并与现有的方法进行比较。实验表明,我们的流形学习方法优于最先进的方法显着。

英文摘要:

Face is one of the most important things for communication with the world around us. It also forms our identity and expressions. Estimating the face structure is a fundamental task in computer vision with applications in different areas such as face recognition and medical surgeries. Recently, deep learning techniques achieved significant results for 3D face reconstruction from flat images. The main challenge of such techniques is a vital need for large 3D face datasets. Usually, this challenge is handled by synthetic face generation. However, synthetic datasets suffer from the existence of non-possible faces. Here, we propose a face manifold learning method for synthetic diverse face dataset generation. First, the face structure is divided into the shape and expression groups. Then, a fully convolutional autoencoder network is exploited to deal with the non-possible faces, and, simultaneously, preserving the dataset diversity. Simulation results show that the proposed method is capable of denoising highly corrupted faces. The diversity of the generated dataset is evaluated qualitatively and quantitatively and compared to the existing methods. Experiments show that our manifold learning method outperforms the state of the art methods significantly.
