Witryna2.1. Hierarchical Implicit Volume Modeling Given a continuous scalar function f : R3 → R+, we can define a volume V: V = n p ∈ R3: f(p) ≥ viso o (1) where viso is called the iso-value. We call V an implicit vol-ume. The surface S of this volume is defined by replacing the inequality in (1) with an equality. We call this surface an ... WitrynaMethod. We use monocular geometric cues predicted by a general-purpose pretrained network to guide the optimization of neural implicit surface models. More specifically, for a batch of rays, we volume render predicted RGB colors, depth, and normals, and optimize wrt. the input RGB images and monocular geometric cues. ean tablet https://fkrohn.com

We propose a novel neural architecture for representing 3D surfaces, which harnesses two complementary shape representations: (i) an explicit representation via an atlas, i.e., embeddings of 2D domains into 3D; (ii) an implicit-function representation, i.e., a scalar function over the 3D volume, with its levels …
