TRIG: Trajectory-Rig Decoupled Metric Geometry Learning
Lizhou Liao, Wentao Xu, Handong Wang +4
Vision-centric autonomous driving requires accurate metric geometry and ego-motion estimation from synchronized multi-camera observations. Recent visual geometry models show strong…
DVD: Deterministic Video Depth Estimation with Generative Priors
Hongfei Zhang, Harold Haodong Chen, Chenfei Liao +12
Existing video depth estimation faces a fundamental trade-off: generative models suffer from stochastic geometric hallucinations and scale drift, while discriminative models demand…
FlowPortal: Residual-Corrected Flow for Training-Free Video Relighting and Background Replacement
Wenshuo Gao, Junyi Fan, Jiangyue Zeng +1
Video relighting with background replacement is a challenging task critical for applications in film production and creative media. Existing methods struggle to balance temporal co…
LINR Bridge: Vector Graphic Animation via Neural Implicits and Video Diffusion Priors
Wenshuo Gao, Xicheng Lan, Luyao Zhang +1
Vector graphics, known for their scalability and user-friendliness, provide a unique approach to visual content compared to traditional pixel-based images. Animation of these graph…
ANYPORTAL: Zero-Shot Consistent Video Background Replacement
Wenshuo Gao, Xicheng Lan, Shuai Yang
Despite the rapid advancements in video generation technology, creating high-quality videos that precisely align with user intentions remains a significant challenge. Existing meth…
Decoupling Bidirectional Geometric Representations of 4D cost volume with 2D convolution
Xiaobao Wei, Changyong Shu, Zhaokun Yue +8
High-performance real-time stereo matching methods invariably rely on 3D regularization of the cost volume, which is unfriendly to mobile devices. And 2D regularization based metho…
