What Matters for 3D Scene Flow Network SpringerLink

WebAbstract. We propose a data-driven scene flow estimation algorithm exploiting the observation that many 3D scenes can be explained by a collection of agents moving as rigid bodies. At the core of our method lies a deep architecture able to reason at the object-level by considering 3D scene flow in conjunction with other 3D tasks. WebOptical flow maps: The optical flow describes how pixels move between images (here, between time steps in a sequence). It is the projected screenspace component of full scene flow, and used in many computer … WebRecent methods [62, 29, 14] such as FLOT [] propose deep neural networks to learn scene flow from point clouds in an end-to-end way, which achieves promising estimation performance. However, estimating scene flow from point clouds is still challenging in two aspects. First, due to the significantly non-uniform density and unordered nature of 3D … do u get deja vu
