Learning to Search for Executable Patternmaking from Certified Programs
Zhuotao Xu, Chi Zeng, Liying Yang +2
Recent models generate sewing patterns from images or text, and program-based representations make these patterns executable. These systems produce a finished pattern and do not mo…
Marrying Optimal Transport and ODEs for Unified Continuous-Time 4D Reconstruction and Tracking
Liying Yang, Hao Mo, Jialun Liu +7
Existing unified 4D reconstruction and point tracking approaches typically rely on heuristic interpolations or just predict at integer timestamps, lacking kinematic coherence and f…
PointCHR: Point Cloud Analysis via Curvature-Aware Hyperbolic Rectification
Xinxing Yu, Liying Yang, Hao Mo +4
High-curvature regions in 3D point clouds encapsulate critical fine-grained geometric semantics yet exhibit a distinct long-tail sparsity in their spatial distribution. The inheren…
Delta-Adapter: Scalable Exemplar-Based Image Editing with Single-Pair Supervision
Jiacheng Chen, Songze Li, Han Fu +5
Exemplar-based image editing applies a transformation defined by a source-target image pair to a new query image. Existing methods rely on a pair-of-pairs supervision paradigm, req…
PointCSP: Cross-Sample Semantic Propagation and Stability Preservation in Self-Supervised Point Cloud Learning
Xinxing Yu, Ajian Liu, Sunyuan Qiang +5
Scene-level point cloud self-supervised learning (PC-SSL) has demonstrated potential in enhancing the generalization capability of 3D vision models. Despite the advances in the fie…
Distilling Future Temporal Knowledge with Masked Feature Reconstruction for 3D Object Detection
Haowen Zheng, Hu Zhu, Lu Deng +3
Camera-based temporal 3D object detection has shown impressive results in autonomous driving, with offline models improving accuracy by using future frames. Knowledge distillation…
SSEditor: Controllable Mask-to-Scene Generation with Diffusion Model
Haowen Zheng, Yanyan Liang
Recent advancements in 3D diffusion-based semantic scene generation have gained attention. However, existing methods rely on unconditional generation and require multiple resamplin…
Distilling Temporal Knowledge with Masked Feature Reconstruction for 3D Object Detection
Haowen Zheng, Dong Cao, Jintao Xu +4
Striking a balance between precision and efficiency presents a prominent challenge in the bird's-eye-view (BEV) 3D object detection. Although previous camera-based BEV methods achi…
