摘要:

本文提出了一种从多视图和单视图图像重建高质量纹理三维模型的方法。重建是一个自适应问题,并逐步完成,在第一阶段,我们专注于学习准确的几何形状,而在第二阶段,我们专注于学习纹理与生成对抗网络。在生成学习管道中,我们提出了两个改进。首先,由于学习的纹理应该在空间上对齐,我们提出了一个注意力机制,依赖于像素的可学习位置。其次,由于P2P接收对齐的纹理映射,我们用可学习的嵌入来增强其输入,从而改善对生成器的反馈。我们在Tripod数据集的多视图序列以及单视图图像数据集Pascal 3D+和CUB上实现了显着改进。我们证明,我们的方法实现了优越的3D纹理模型相比,以前的作品。请访问我们的网页获取3D视觉效果。

英文摘要:

This paper presents a method to reconstruct high-quality textured 3D models from both multi-view and single-view images. The reconstruction is posed as an adaptation problem and is done progressively where in the first stage, we focus on learning accurate geometry, whereas in the second stage, we focus on learning the texture with a generative adversarial network. In the generative learning pipeline, we propose two improvements. First, since the learned textures should be spatially aligned, we propose an attention mechanism that relies on the learnable positions of pixels. Secondly, since discriminator receives aligned texture maps, we augment its input with a learnable embedding which improves the feedback to the generator. We achieve significant improvements on multi-view sequences from Tripod dataset as well as on single-view image datasets, Pascal 3D+ and CUB. We demonstrate that our method achieves superior 3D textured models compared to the previous works. Please visit our web-page for 3D visuals.
