FPSGen: Flexible Point Cloud Scene Generation with BEV-Supported Transport Flows
Wenzhe He, Meng Wang, JiaWei Qian +3
FPSGen is a framework that generates outdoor point‑cloud scenes by first predicting a bird’s‑eye‑view prior and then using a transport‑flow model to create points, supporting both…
PortraVec: Image-Based Portrait Vectorization with Text-Guided Manipulation
Yiqi Liang, Ying Liu, Dandan Long +1
While portrait sketch generation is a special task in sketch synthesis, most existing methods are pixel-based, limiting their interpretability and editability. With the rise of vec…
PointSLAM++: Robust Dense Neural Gaussian Point Cloud-based SLAM
Xu Wang, Boyao Han, Xiaojun Chen +2
Real-time 3D reconstruction is crucial for robotics and augmented reality, yet current simultaneous localization and mapping(SLAM) approaches often struggle to maintain structural…
RWKV-PCSSC: Exploring RWKV Model for Point Cloud Semantic Scene Completion
Wenzhe He, Xiaojun Chen, Wentang Chen +3
Semantic Scene Completion (SSC) aims to generate a complete semantic scene from an incomplete input. Existing approaches often employ dense network architectures with a high parame…
MROSS: Multi-Round Region-based Optimization for Scene Sketching
Yiqi Liang, Ying Liu, Dandan Long +1
Scene sketching is to convert a scene into a simplified, abstract representation that captures the essential elements and composition of the original scene. It requires a semantic…
