VideoReloc: Long-Term Indoor Video Relocalization against a Kilobyte-Scale Semantic Scene Graph
Qianru Li, Xuyang Chen, Xuqin Wang +6
Given a compact semantic scene graph, long-term indoor video relocalization estimates a map-frame trajectory after lighting and furniture changes. Visual methods rely on appearance…
CinemaTraj: Composing Atomic Camera Trajectories for 3D Scenes with LLM Agents
Qianru Li, Xuyang Chen, Erkin Türköz +5
Automatically generating cinematically expressive camera trajectories through 3D scenes from natural language descriptions is a challenging task of high practical value, with appli…
Driving with DINO: Vision Foundation Features as a Unified Bridge for Sim-to-Real Generation in Autonomous Driving
Xuyang Chen, Conglang Zhang, Chuanheng Fu +9
Driven by the emergence of Controllable Video Diffusion, existing Sim2Real methods for autonomous driving video generation typically rely on explicit intermediate representations t…
Constructing coherent spatial memory in LLM agents through graph rectification
Puzhen Zhang, Xuyang Chen, Yu Feng +2
Given a map description through global traversal navigation instructions, an LLM can often infer the implicit spatial layout and answer user queries by providing shortest paths. Ho…
MeSS: City Mesh-Guided Outdoor Scene Generation with Cross-View Consistent Diffusion
Xuyang Chen, Zhijun Zhai, Kaixuan Zhou +11
Mesh models have become increasingly accessible for numerous cities; however, the lack of realistic textures restricts their application in virtual urban navigation and autonomous…
Box2Poly: Memory-Efficient Polygon Prediction of Arbitrarily Shaped and Rotated Text
Xuyang Chen, Dong Wang, Konrad Schindler +4
Recently, Transformer-based text detection techniques have sought to predict polygons by encoding the coordinates of individual boundary vertices using distinct query features. How…
