Latent Appearance Modeling 还是用到了GLO的方法(generative latent optimization),对每张图生成一个相关的latent code也叫做appearance embedding。 把原始NeRF中的c(t)换成了ci(t),这个意思是说,要强调颜色c对每张图的依赖性。他认为原来的c和图片标号没有关系,但是在这里ci介入了一种像素对应图片的依赖性,因为每...

Update:NeRF-W(NeRF in the Wild) implementation is added tonerfwbranch! Update: The lastest code (using the latest libraries) will be updated todevbranch. The master branch remains to support the colab files. If you don't use colab, it is recommended to switch to dev branch. Only issues...
The code is largely based on NeRF implementation (see master or dev branch), the main difference is the model structure and the rendering process, which can be found in the two files under models/. 💻 Installation Hardware OS: Ubuntu 18.04 NVIDIA GPU with CUDA>=10.2 (tested with 1 RTX20...
NeRF系列(2):NeRF in the wild : Neural Radiance Fields for Unconstrained Photo Collections论文解读与公式推导_LeapMay的博客-CSDN博客 我们提出了一种基于学习的方法,利用非结构化的野外照片集合合成复杂场景的新视角。我们在神经辐射场(NeRF)的基础上进行了改进,以解决在真实世界的图像中存在的光照和遮挡等问题。
NeRF-W (“in the wild”), an influential early paper, proposed two ideas: Exclude transient objects by training two scenes: a common static scene (shared between all views) and a transient scene (one per each view). Introduce alighting latent variable, a multidimensional vector to encode the...
它基于渲染加速,还做了两个优化工作,分别是empty space skipping以及hybrid volume-surface rendering,这两个措施其实属于常规操作,其中volume-surface rendering在 Neural 3D Reconstruction in the Wild 这篇工作中看到类似的,可以理解为先求光线与物体相交的位置(hit point),再基于hit point向光线方向进行采样,这样...
