In this paper, we propose a generalization of SSMs, called Gaussian Process Morphable Models (GPMMs). We model the shape variations with a Gaussian process, which we represent using the leading components of its Karhunen-Loeve expansion. To compute the expansion, we make use of an approximation...

2401.08140——ProvNeRF: Modeling per Point Provenance in NeRFs as a Stochastic Process 神经辐射场(NeRFs)在各种应用中变得流行。然而,它们在稀疏视图设置中面临挑战,缺乏来自体积渲染的足够约束。从稀疏和不受限制的相机中重建和理解3D场景是经典计算机视觉中长期存在的问题,有着各种各样的应用。尽管最近的工作已经...
Gaussian Process Morphable Models (GPMMs) are a unifying approach to non-rigid surface and image registration, where a deformation prior is defined using a Gaussian process. By a simple exchange of the covariance function we can formulate a wide variety of different deformation priors, such as sp...
