3. Dynamic Image-Based Rendering 给定一个具有帧的动态场景的单目视频(I1, I2,…,, IN ) 和已知的相机参数 (P1, P2,., PN ),目标是在视频中任何所需时间合成一个新的视点。与许多其他方法一样,此方法训练每个视频,首先优化模型来重建输入帧,然后使用该模型渲染新视图。 不像最近的动态NeRF方法那样直接...

Human re-rendering from a single image is a starkly under-constrained problem, and state-of-the-art algorithms often exhibit undesired artefacts, such as over-smoothing, unrealistic distortions of the body parts and garments, or implausible changes of the texture. To address these challenges, we...
The present invention relates to a method for generating a 3D virtual space based on neural rendering and a server for the same. Specifically, the present invention relates to a method for removing dynamic objects from a 2D image and then obtaining a spatial image, and generating the above 2D...

volume rendering的缺点主要在于有限制的分辨率。使用体素(voxel-based)的数据结构通常来说比基于mesh的数据结构需要多一个数量级的内存来达到相似的分辨率。此外,很多内存被用来保存空的空间,或者不可见的空间,这些都是对渲染没有作用的部分。 为了战胜这个缺点,Lombardi采用了warpingtechnique,来间接摆脱regular grid struc...
