3D Mesh Generator使用轮廓图像进行训练,如下图。 Generator试图在训练阶段最小化重建 3D 形状的轮廓与真实轮廓之间的loss。2D 到 3D 风格转换是通过优化网格的形状和纹理来执行的,以最大限度地减少图像上定义的风格损失。 3D DeepDream 也以类似的方式执行。这两个应用程序都是通过Nueral Render将 2D图像空间中的...
This repo contains a PyTorch implementation of the paperNeural 3D Mesh Rendererby Hiroharu Kato, Yoshitaka Ushiku, and Tatsuya Harada. It is a port of theoriginal Chainer implementationreleased by the authors. Currently the API is the same as in the original implementation with some smalls additio...

NeMo用了Render-and-Compare(也是Analyze-by-Synthesis)的方法进行物体姿势估计,具体而言,不同于直接在forward的时候输出3D object pose,这类方法在pose estimation的过程中会不断的生成图像,并通过比较生成的图像和testing image来调整当前的pose prediction。如下图:...
Mesh:表面是由一个个三角形组成 Point cloud:点云 Occupancy field:对三维空间中的每一个点,如果这个点被物体占有,则把这个点的value设置为1 Signed distance field:对三维空间中的每一个点,把这个点的value设置为到物体最近表面的距离,区分正负,图中蓝色为负 ...
同时设计了一种融合多种view信息的方法 输入数据是 3D mesh 怎么生成 view: Phong reflection model (别人提出的模型) Retrievel 设计的目标函数 需要计算nx\timesnynx\timesny次 这样效率不高, 所以学习自动合成所有的view特征就会提高效率 Result

We leverage volumetric neural rendering [28, 4] for realistic rendering; our method achieves higher rendering quality than other neural render- ing methods [42, 43]. Mesh-based reconstruction and rendering. 3D polygo- nal meshes are one of the most popular geometry re...
This can be done because it is based on a fixed UV parameterisation setting that maps points on the 3D mesh surface to 2D UV planes. After encoding the latent code Y, local details can be captured by the , and these details can be used to infer local geometric and appearance variations...
