A well-designed vectorized representation is crucial for the learning systems natively based on 3D Gaussian Splatting. While 3DGS enables efficient and explicit 3D reconstruction, its parameter-based representation remains hard to learn as features, especially for neural-network-based models. Direct…
Point cloud single object tracking is critical in autonomous driving. However, current methods heavily rely on frame-by-frame human annotations, which do not scale well with the growing amount of unlabeled LiDAR data. In this paper, we propose the first self-supervised point cloud single object trac…
We propose tttLRM, a novel large 3D reconstruction model that leverages a Test-Time Training (TTT) layer to enable long-context, autoregressive 3D reconstruction with linear computational complexity, further scaling the model's capability. Our framework efficiently compresses multiple image observat
Three-dimensional scene generation is crucial in computer vision, with applications spanning autonomous driving and gaming. However, current methods offer limited or non-intuitive user control. In this work, we propose a method that uses scene graph as a user-friendly control format to generate outd…
Established sampling protocols for 3D point cloud learning, such as Farthest Point Sampling (FPS) and Fixed Sample Size (FSS), have long been relied upon. However, real-world data often suffer from corruptions, such as sensor noise, which violates the benign data assumption in current protocols. As
