ARSGaussian: 3D Gaussian Splatting with LiDAR for Aerial Remote Sensing Novel View Synthesis

This paper introduces ARSGaussian, a novel view synthesis method for aerial remote sensing that integrates LiDAR constraints, distortion-aware coordinate transformations, and geometric consistency losses to mitigate floaters and overgrowth while achieving high-precision geo-alignment, supported by the newly released AIR-LONGYAN dataset.

Collaborative Problem Solving in Mixed Reality: A Study on Visual Graph Analysis

This study involving 72 participants across three languages demonstrates that while nominal groups serve as a crucial benchmark for evaluating collaborative virtual environments, 3D graph representations in mixed reality do not inherently yield better collaborative problem-solving outcomes than individual performance.

A comprehensive study of time-of-flight non-line-of-sight imaging

This paper presents a comprehensive study of Time-of-Flight non-line-of-sight imaging methods by unifying their theoretical formulations and hardware implementations to establish a common framework for analysis and demonstrate that, under equal constraints, existing techniques share similar performance limitations despite method-specific differences.

M-ABD: Scalable, Efficient, and Robust Multi-Affine-Body Dynamics

This paper introduces M-ABD, a scalable and robust framework that leverages linear kinematic mapping and a compact dual-space formulation of Affine Body Dynamics to enable interactive, stable simulation of large-scale articulated assemblies with hundreds of thousands of bodies on a single CPU core.

Retrieval-Augmented Gaussian Avatars: Improving Expression Generalization

The paper introduces RAF (Retrieval-Augmented Faces), a training-time augmentation method that enhances the expression generalization and robustness of template-free animatable head avatars by dynamically replacing subject features with nearest-neighbor expressions from a large unlabeled bank, thereby improving fidelity in both self-driving and cross-driving scenarios without requiring additional data or architectural changes.

TreeON: Reconstructing 3D Tree Point Clouds from Orthophotos and Heightmaps

TreeON is a novel neural framework that reconstructs detailed 3D tree point clouds from a single orthophoto and Digital Surface Model by leveraging a synthetic dataset and a unique training strategy combining geometric, shadow, and silhouette losses to achieve high-quality, generalizable results without requiring ground truth data or species labels.
