Neural Scene Representations for 3D Reconstruction and Scene Understanding

, 2023
In an era where machines are increasingly integrated into our daily lives, their ability to perceive and understand the three-dimensional world becomes of great importance. Central to this capability is the scene representation, which translates sensory data into compact, detailed, and holistic descriptions of the environment.

Semantic Scene Completion With 2D and 3D Feature Fusion

IEEE Access
3D semantic scene completion (SSC) aims to get a dense semantic understanding of an environment in 3D. It requires a geometric and semantic knowledge of the surrounding environment and the filling of void areas.

Progressive Camera-LiDAR Adaptation for Scene Flow Estimation [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
3D scene flow aims to recover the dense geometry and 3D motion of dynamic scenes. This paper explores the transformation and adaptation of the 2D-3D feature space in the joint estimation of optical flow and scene flow.

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...
