Gaussian Blending: Rethinking Alpha Blending in 3D Gaussian Splatting

The paper presents a novel approach to 3D Gaussian super-resolution, addressing the limitations of existing methods that operate at fixed scale factors. The proposed framework integrates scale-aware rendering, generative prior-guided optimization, and progressive super-resolving, allowing for high-resolution rendering of arbitrary scale factors using a single 3D model. Experimental results indicate a significant improvement in rendering quality, achieving a PSNR gain of 6.59 dB over traditional methods.

RoboTidy is a new benchmark designed for language-guided household tidying, addressing the limitations of current benchmarks that fail to model user preferences and support mobility.

Gaussian See, Gaussian Do is a new method for semantic 3D motion transfer from multiview video. This approach allows for rig-free, cross-category motion transfer between objects that have semantically meaningful correspondence. By utilizing implicit motion transfer techniques, the method extracts motion embeddings from source videos and applies them to static target shapes, resulting in improved motion fidelity and structural consistency in 3D Gaussian Splatting reconstruction.

The paper presents SymGS, a novel framework for compressing 3D Gaussian Splatting data by leveraging local symmetries.

The paper 'Gaussian Mapping for Evolving Scenes' introduces a dynamic scene-adaptation mechanism that enhances 3D Gaussian Splatting (3DGS) for applications in computer vision, augmented reality, robotics, and autonomous driving. This mechanism continuously updates 3DGS to reflect changes in evolving scenes, addressing the limitations of existing methods that primarily focus on static scenes. A novel keyframe management system is proposed to discard outdated observations while retaining essential information.

Sparse-view synthesis presents challenges in accurately recovering geometry and appearance from limited observations. Recent advancements in 3D Gaussian Splatting (3DGS) have improved real-time rendering quality, yet existing methods often depend on Structure-from-Motion (SfM) for camera pose estimation, which is ineffective in sparse-view scenarios. The proposed Segmentation-Driven Initialization for Gaussian Splatting (SDI-GS) addresses these inefficiencies by utilizing region-based segmentation to focus on structurally significant areas, allowing for effective downsampling of dense point cl…

The paper presents a novel approach to modeling hand-object interactions in dynamic scenes without relying on object priors. It introduces interaction-aware hand-object Gaussians with optimizable parameters to improve structural representation. The method incorporates hand shape into the object deformation field to model flexible motions and employs a progressive optimization strategy to address challenges in dynamic regions and static backgrounds.

Image-Based Gaussian Splatting (IBGS) is a novel approach to 3D Gaussian Splatting (3DGS) that enhances novel view synthesis (NVS) by utilizing high-resolution source images. This method addresses limitations in capturing spatially varying colors and view-dependent effects, such as specular highlights, which are often hindered by low-degree spherical harmonics. By modeling pixel colors as a combination of base colors and learned residuals from neighboring images, IBGS promotes accurate surface alignment and enables the rendering of high-frequency details.
